“…Thermoelectric power being sensitive to the energy dependence of the electron lifetime and the density of states near the Fermi level energy, provides valuable information regarding many fundamental aspects of charge carrier transport in the materials. The thermoelectric power (S) of high-temperature superconductors has been widely studied and reported a positive 'S', while Khim et al (Khim et. al.…”

“…One should note that the magnetic measurements in low field (Fig. lb) show that the decrease of X below Tc seems to be less steep for lower Tc [27]). The Hall effect has also been found ptype in the Y compound [28], either in sintered powder or in epitaxial thin films, for magnetic field parallel to the c-axis [29].…”

Sintered powders of SmBa2Cu3O7-x have been prepared and characterized. The physical properties, superconducting temperature transition, up to 92 K, magnetic susceptibility, electrical resistivity and thermopower have been studied as a function of the preparation conditions and therefore of oxygen stoichiometry. The upper critical field has been estimated from resistivity measurements in fields up to 8 T and the slope (dBc2/dT)Tc found to be close to 4 TK-1 for the highest Tc samples. Studies of the electrical resistivity under hydrostatic pressures up to 18 kbar show an increase of Tc under pressure with dTc/dp ∼ 0.5 K kbar-1. Finally measurements of voltage-current characteristics indicate that either Josephson junctions or superconductor-insulator-normal metal junctions can be found inside the samples, as expected in inhomogeneous materials
