 PLEASE READ: The electronic-mail version of High-Tc Update is generated
 from a Macintosh Microsoft Word file and turned into a text file that
 can be transferred electronically. Formatting commands, Greek symbols,
 diacritical marks, etc. are lost in this transformation. In order to
 improve the readability of the e-mail version, the newsletter staff add
 explanatory marks as needed to the text file. For example, a carat
 (10^5) indicates a superscript (ten to the fifth). A carat followed by
 a bracket (cm^[-2]) indicates everything within the brackets is
 superscripted (centimeter to the minus 2). A bracket followed by a
 carat ([18]^O) indicates everything before the carat is superscripted.
 An underline (M_i) indicates a subscript (M subscript i). Most Greek
 letters are spelled out (Delta, mu, tau, pi, Omega), although delta is
 left as "d." In most instances, easily recognizable formulas or units
 are left as they appear: Tc, Jc, YBa2Cu3O7, O2. Mu-m is changed to
 micrometers. Diacritical marks (accents, tildes, carats, etc.) are
 removed, but the German umlaut (e.g., a, o, or u with two dots over it)
 is changed into a, o, or u followed by e. If needed for clarity,
 hyphens are occasionally inserted between spelled-out Greek letters or
 symbols (ohm-cm, sin-theta).

<p>
<p>
 Rare Earth Cuprates
<p>
 Andreev bound states in Y-123 have been studied by M. Aprili et al.
 (Urbana). Changes in the zero-bias conductance peak with magnetic field
 indicate that the low-bias conductance conserves the number of states,
 and that the magnitude of the magnetic-field-induced splitting is
 dependent on field orientation. This is consistent with the Folgestrom-
 Rainer-Sauls model in which the splitting is due to a Doppler shift
 arising from the scalar product between the quasiparticle velocity and
 the superfluid momentum.
<p>
 A comparison of the zero-bias conductance peak for several cuprate
 superconductors by L. Alff (Koeln) et al. has been related to the
 symmetry of the wave function. The zero-bias peak was observed only in
 systems with a d-wave symmetry, but was absent for the s-wave Nd-Ce
 system.
<p>
 High-pressure experiments with Pr-123 by J. Ye (NRIM) et al. reveal a
 parallelism between the pressure dependence of Tc for superconducting
 Pr-123 and that of Y-123. For these samples grown by the traveling-
 solvent float-zone method, Pr-123 seems to be an ordinary member of the
 RE-123 superconducting family.
<p>
 Hall-angle measurements have been used by Y. Abe (University of Tokyo)
 et al. to look for pseudogap effects in Zn-doped Y-123. Deviations of
 the cotangent of the Hall angle from T2 behavior suggests that the
 pseudogap affects the Hall angle through a change in the effective mass,
 rather than through a change in the Hall scattering rate.
<p>
<p>
 Bi-Cuprates
<p>
 Microstructural and transport properties of electrophoretically
 deposited Bi-2212/Ag tape composites were studied by S.-L. Huang and D.
 Dew-Hughes (Oxford) to determine the effects of various heat treatments
 on critical current performance and the distribution of alkaline-earth
 cuprate phases. Processing conditions were found that are favorable for
 the industrial manufacture of tape conductors.
<p>
 The microstructural and superconducting properties of Hg-doped Bi-2212
 were studied by A. Matsumoto et al. (NRIM) in order to study the effects
 of small pinning centers. The Hg substitution enhanced Tc up to 97 K,
 but the intergrain coupling was diminished by the presence of Hg.
 Critical currents, as measured by magnetic hysteresis, systematically
 decreased by about an order of magnitude for each ten percent decrease
 in Tc.
<p>
 Changes in the transport Jc of Bi-2223 tapes was studied by D. M.
 Spiller (Southampton) et al. to determine the effect of excess Bi-2212
 added to the normal Bi-2223 stoichiometry. The addition of 10% Bi-2212
 to the Endo composition for Bi-2223 can increase Jc by about a factor of
 four. They conclude that improvement of grain-boundary quality rather
 than the introduction of pinning centers leads to the enhancement of Jc.
<p>
 As reported by A. Bianconi (Rome) et al., angular resolved photoemission
 has been used to study non-Fermi-liquid behavior and diagonal lattice
 stripes in cuprate Bi-2212 superconductors. The line shape of the
 energy-distribution curves show a spectral function expected for a non-
 Fermi-liquid behavior. The Fermi surface contour in the "even symmetry"
 reveals the suppression of spectral weight due to coupling with joint
 incommensurate charge density wave in the diagonal direction and the
 spin density wave at G(pi,pi).
<p>
 A study of the Y NMR has been carried out by A. G. Kontos et al.
 (Coventry) for Y substituting for Ca in Bi-2212. The resonance of Y on
 the Ca site shifts diamagnetically upon increasing the carrier
 concentration and paramagnetically upon reducing the temperature, in
 close relation with the variation of Tc in the system.
<p>
 The in-plane and out-of-plane magnetoresistance of Bi-2212 single
 crystals has been studied by G. Heine (Vienna) et al. The in-plane
 magnetoresistance is positive for all temperatures and magnetic fields.
 Near Tc, the in-plane magnetoresistance is dominated by theromdynamic
 fluctuations, but at higher temperatures, a smooth transition to the
 normal-state quasiparticles takes place. In sharp contrast, the out-of-
 plane magnetoresistance is negative for all temperatures and
 orientations of the magnetic field. The data are interpreted in the
 framework of superconducting fluctuation theory.
<p>
<p>
 Other Cuprates
<p>
 Synchrotron radiation x-ray studies have been used by C. Rial (Madrid)
 et al. to follow in real time the evolution of oxygen during a thermal
 treatment to convert La-214 into the oxygen-rich La-214 phase. The
 stability of the oxygen-rich phase seems to be due to the presence of
 one-dimensional interstitial oxygen ordering along the c-axis, as
 suggested by the appearance of a pair of superlattice satellite peaks
 around the mixed parity (012) peak.
<p>
 High-pressure measurements have been undertaken by S. Sadewasser
 (Washington University) et al. in order to study time-dependent changes
 in Tc that occur as atoms diffuse after a change in pressure for
 HgBa2CuO4. Results show weak relaxation effects in strongly underdoped
 and overdoped samples with an activation energy of 0.8-0.9 eV. For the
 Hg compound, the activation energy increases with pressure more rapidly
 than it does in Y-123.
<p>
 Neutron-diffraction refinement measurements were undertaken by M.
 Karppinen (Yokohama) et al. to determine the relative effectiveness of
 doping Cu-1212:P with Ca and with excess oxygen. Oxygen doping was
 found to increase hole concentration less efficiently than Ca doping and
 higher Tc values were obtained with Ca additions than could be obtained
 with oxygen alone. These two doping methods also gave different Tc vs
 Cu-O bond-length relations.
<p>
<p>
 Other Superconductors
<p>
 As reported by A. Amici et al. (Dresden), an extended BCS theory may be
 constructed in the general case of commensurate magnetic structures such
 as those illustrated by the borocarbides. In the special case of
 helical magnetic order, the extended theory is also valid in the
 incommensurate limit. They suggest an explanation for the anomalies of
 the Ho borocarbide data.
<p>
<p>
 Films
<p>
 The effect of the patterning process on the microwave surface impedance
 of Y-123 thin films was investigated by H. Xin (MIT) et al. With the
 use of a sapphire dielectric resonator and a stripline resonator, the
 microwave surface impedance of Y-123 was measured before and after the
 patterning process. Experimental and modeled results show that the
 patterning has no observable effect on the value of R_s or on the power
 dependence of R_s.
<p>
<p>
 Applications
<p>
 SQUID measurements were used by G. Wuebbeler (Berlin) et al. to study
 the dc ionic currents that are generated after the injury of a nerve.
 The device used mechanical modulation of the source-to-detector distance
 to extend the frequency range below 0.1 Hz. Magnetic field changes of
 10 fT were resolved in measuring times of 100 s. Injury related near-dc
 biomagnetic fields were recorded in-vivo with a patient undergoing a
 diagnostically indicated muscle biopsy.
<p>
 A Josephson array oscillator with microstrip resonators for the
 submillimeter region was developed by A. Kawakami et al. (Kobe). The
 Josephson array oscillators were designed and fabricated to operate near
 the Nb gap of 700 GHz using 11 shunted Nb/AlOx/Nb junctions with Nb
 microstrip resonators. Using the RLCSJ model, the outpower of the
 Josephson oscillator was estimated to be about 0.1 microwatt at 680 GHz.
<p>
 A superconducting 4-bit instantaneous frequency meter on a 2" MgO wafer
 has been constructed for operation in the 10 GHz range by M. Biehl et
 al. (Karlsruhe). Due to integration of power-divider resistors and a
 large number of air bridges, improved transmission characteristics are
 achieved in a more reproducible way than with surface-mounted chip
 resistors and ultrasonically bonded air-bridges.
<p>
<p>
 Theory
<p>
 The effects of charging and of Josephson plasma resonance on the complex
 resistivity of high-temperature superconductors has been determined by
 A. Gurevich (Madison) and M. Tachiki (NRIM). They show that planar
 crystalline defects parallel to the ab-plane can give rise to a
 localized Josephson plasma mode formed by a collective Coulomb
 interaction of interlayer junctions. This results in a pronounced
 satellite line in the real part of the complex resistivity. The
 position and amplitude of the line depend on the critical current
 density and on the parameters of the charge interlayer coupling. The
 narrowness of the zero-field plasma peak enables one to probe the
 pairing symmetry of the interlayer coupling.
<p>
 A comparison of superconductivity in Sr2RuO4 and the copper oxides has
 been made by E. V. Kuz'min and S. G. Ovchinnikov (Krasnoyarsk). They
 present a model of strongly correlated electrons in a two-dimensional
 lattice that allows the cuprates with antiferromagnetic coupling and the
 Sr2RuO4 with ferromagnetic coupling to be considered on the same
 footing. Singlet superconductivity in the s-state is absent in the
 strong-correlation limit. The triplet p-pairing occurs due to the
 ferromagnetic fluctuations and the singlet d-pairing is induced by the
 antiferromagnetic fluctuations.
<p>
 Resonant inelastic x-ray scattering in insulating cuprates is examined
 by K. Tsutsui et al. (Tohoku) using the exact-diagonalization technique
 on small clusters in the two-dimensional Hubbard model with second- and
 third-neighbor hopping terms. When the incident photon energy is tuned
 near the absorption edges, they find that the features of the unoccupied
 upper Hubbard band can be extracted from the x-ray spectrum through an
 anisotropic momentum dependence. Results provide an opportunity for the
 understanding of the different behavior of hole- and electron-doped
 superconductors.
<p>
 A spin-wave theory of short-range order in the square-lattice Heisenberg
 antiferromagnet is formulated by A. Sherman (Tartu) and M. Schreiber
 (Chemnitz). With growing temperature from T = 0, a gapless mode is
 shown to arise simultaneously with opening a gap in the conventional
 spin-wave mode.
<p>
 The effect of thermal phase fluctuations on the inductances of Josephson
 junctions, arrays of junctions, and thin films has been calculated by T.
 R. Lemberger et al. (Ohio State). They find that quantum mechanics
 supresses fluctuations when the temperature drops below a character-
 istic temperature controlled by the shunt conductance and the mean-field
 inductance. They find that thermal phase fluctuations are much more
 important than phase-slip fluctuations, except very close to the super-
 to-normal transition.
<p>
 A paper by G. Khaliullin (Dresden) et al. reports a theory of the local
 spin polarization in the underdoped cuprates with Ni and Zn impurities
 substituted into the planar Cu sites. Both types of impurity induce
 moments on the neighboring Cu sites. In the case of Ni, these moments
 partially screen the inherent impurity spin resulting in an effective S
 = 1/2 moment. They investigate the spatial shape of the impurity-
 induced spin density.
<p>
 The Raman response function in the weak-coupling limit has been
 calculated by D. Manske (Berlin) et al. for a clean d-wave
 superconductor below Tc using various approaches for the bare coupling
 between the incident light and the electronic excitations. Within a
 one-band description, it turns out that the A_[1g] and B_[2g] scattering
 intensities depend strongly on band-structure effects.

 Feb. 20 - Feb. 25, 2000: Sixth International Conference on Materials
 and Mechanisms of Superconductivity and High Temperature Superconductors
 (M2S-HTSC-VI), George R. Brown Convention Center, Houston, Texas.
 Hosted by the Texas Center for Superconductivity at the University of
 Houston and sponsored by federal agencies and industry. Co-Chairs: C.
 W. Chu, W. K. Chu and K. Salama. This series of meetings, established
 in 1988 two years after the discovery of high-temperature
 superconductors, is dedicated to superconductivity and related
 phenomena, and the host materials of these phenomena. The Conference
 will bring together members of the international low- and high-
 temperature superconductivity community to focus on recent insights into
 low- and high-temperature superconductor physics, materials, and
 devices. Emerging areas and future trends will also be highlighted.
 General conference topics include, but are not limited to, experimental
 and theoretical studies of Superconducting Materials -- low temperature,
 high temperature, fullerite, heavy fermion, organic, new; Physical
 Properties -- mechanisms, magnetic, electrical, optical, thermal,
 mechanical, acoustic; Synthesis and Processing -- thin films,
 superlattices, thick films, bulk; and Applications -- small current
 (SQUIDs, junctions, microwave devices) and large current (cables,
 transformers, motors, generators, magnetic levitation devices).
