Аннотация: The results of electronic structure calculations of the CuO2 layer, performed by the generalized tight-binding method, are presented. The strong electron correlations on both the Cu and O ions are included explicitly. The resulting quasiparticle band structure contains an insulator gap for undoped compounds like La2CuO4. The valence band consists of a large number of narrow Hubbard quasiparticle bands. The dispersion law of quasiparticles at the top of the valence band has a minimum at the GAMMA-point, indicating the existence of the multivalley Fermi surface in the doped La2-xSrxCuO4. The origin of the Fermi liquid behavior in the narrow quasiparticle bands is discussed.

Ключевые слова (''Своб.индексиров.''): ceramic materials--crystals--ferroelectricity--phase diagrams--order parameters--oxide superconductors--high temperature superconductors
Аннотация: Using group-theoretical methods it is shown that improper ferroelectric phase may arise in high-temperature superconductors (HTSC) where high-symmetry phases have space groups D4h1 or D4h17. Their appearance is caused by condensation of order parameters (OP's) transforming two irreducible representations (IR's). The most typical phase diagrams are considered, as well as temperature dependence of OP's and the basic structural mechanism of the ferroelectricity arising in the HTSC.

Аннотация: A model of a superconducting fault current limiter on a polycrystalline high-temperature superconductor basis is checked in the dc short circuit regime. Protection of load takes place under the conditions described in this paper. The use of ceramic materials with superconducting-normal metal-superconducting Josephson junction network having an S-type current-voltage characteristic (CVC) is shown to be effective for fault current limiter devices.

Аннотация: We have studied the magnetoresistive effect in bulk 1-2-3 YBCO + CuO and 1-2-3 YBCO + BaPb1-xSnxO3 composites prepared using the fast backing technique. We have found that the composites exhibit large magnetoresistance in low magnetic fields ( 100 Oe) for a broad temperature range. We have studied the experimental dependences of resistivity versus magnetic field at various transport current densities. The high-T-C superconductor (HTSC) based composites exhibit a much higher sensitivity to weak magnetic fields at liquid nitrogen temperature, compared to that for pure HTSC ceramics. This effect is attractive for practical applications and the composite materials can be used as active elements in magnetic field sensor devices.

Аннотация: The angular dependence of the magnetoresistance of polycrystalline Y3/4Lu1/4Ba2Cu3O7-CuO composites has been studied. These composites represent a system of Josephson junctions and exhibit a large magnetoresistance at 77 K. In addition to the isotropic component, there is the angle-dependent component proportional to sin(2)theta, where theta is the angle between the directions of current and magnetic field. This behavior is unambiguous evidence for the process of flux flow in the Josephson medium realized in the composites.

Аннотация: For Ba0.9Bi0.067(Ti1-xZrx)O-3 (x = 0.04, 0.15) ceramics, the heat capacity C-p(T) and the thermal expansion alpha(T) were measured using an adiabatic calorimeter and an optical-mechanical dilatometer in the temperature range 100-420 K. Both compounds reveal diffuse heat capacity and thermal expansion anomalies: three anomalies in the temperature regions 150-250 K, 250-300 K (alpha(T) only) and 300-400 K at x = 0.04 and two anomalies in the regions 200 250 K and 250-350 K at x = 0.15. The results obtained are discussed together with the data on the dielectric properties.
