We report on the ab-plane polarized reflectance of an untwinned (Bi1.57Pb0.43)Sr2CaCu2O8+delta single crystal over the frequency range from 80 to 32 000 cm(-1) (10 meV-4 eV) at temperatures between 10 and 300 K. We find a clear anisotropy in the ab-plane o ...
It is first shown that the thermal fluctuation effects on the transport and on the thermodynamic observables above the superconducting transition may provide, when they are analyzed simultaneously and consistently, a powerful tool to access the relaxation ...
The ab-plane optical properties of the high-temperature superconductor Bi2Sr2CaCu2O8 are anisotropic in both the normal and the superconducting state. Consistent with the orthorhombic structure, the principal axes lie along the a and b crystallographic axe ...
We calculate the one-particle spectral functions above the superconducting transition temperature TC, in the framework of a functional integral approach. The coupling of the electronic self-energy to pair fluctuations, which are treated by means of a time- ...
We investigated the effect of disorder on the spectral properties of the high temperature superconductor Bi2Sr2CaCu2O8+x. We find that small defect densities, in the low 10(-3) range, already suppress the characteristic spectral signature of the supercondu ...
The surface impedance of type-II superconductors in the mixed state has been studied, taking into account the vortex elasticity and nonlocality (long-range interaction of vortices). An electromagnetic wave penetrates into a superconductor as a superpositio ...
We have studied electronic properties of (YBa2Cu3O6.9)1-xAgx compounds with 5, 10, 15, 25 and 50 wt% Ag. In our samples, the silver fills the intergranular space and the superconductivity is preserved even at 50 wt% Ag(Tc=87 K). These samples can be safely ...
We present the resistivity measurements on single crystals of Sr2RuO4-delta, grown by the flux technique. We discuss the striking, linear temperature dependence of resistivity that persists up to similar to 1050 K. The superconductivity in this system is c ...
