“…These values are consistent with those reported for Bi2223 superconductors [4,8,21,23,24]. A transition to the superconducting state begins at 115 Kindependent of the magnetic field strength as revealed by the resistivity derivative.…”

“…The normal state thermoelectric power varies linearly with temperature at an average slope of −5×10 −8 V K −2 , as typ- ically observed for Bi-based HTSC [4,8,9,14,20,21,25]. The maximal TEP of 27 µV K −1 is attained just above the superconducting transition starting at about 110 K and is followed by a decrease at lower temperatures (figure 5).…”

“…We cannot list the various routes for producing HTS superconductors nor mention all papers pertaining to studies of magnetotransport in HTS The basic references which we can mention below without excessively increasing the list will therefore only be at the intersection of reports concerned with magnetotransport, films and Bi-based systems. We thus quote [20][21][22][23][24][25][26]. As a pioneering and quite thorough investigation that of Dascoulidou and co-workers [23] is probably the most relevant.…”

Various physical properties of a high-pressure made Bi 1.84 Pb 0.34 Sr 1.91 Ca 2.03 Cu 3.06 O x ceramic have been studied in the normal state and mixed state region, mainly from the point of view of transport properties. The electrical resistivity, the thermoelectric power and the Nernst effect are reported for a broad temperature range and for fields between 0 and 4 T. Derived physical parameters like the excess (integrated) properties, the behaviour of the percolation line(s) as a function of temperature and field, the so-called transport energy, and the so-called activation energies, the Ginzburg-Landau parameter and the thermal Hall angle field and temperature dependence are given and briefly compared with previous reports. We point out that in the region examined, the so-called percolation lines differ whether the transport coefficient is purely electrical or is electrothermal in nature. We point out that the 90 • thermal Hall angle temperature is the same as the thermoelectric percolation temperature. Finally we examine for the first time in such systems the behaviour of the so-called 'electrothermal conductivity'. Through a kinetic formalism using either an s-wave or a d-wave-like order parameter, we point out that the field dependence is quite different in the mixed state near the critical temperature. This allowed us to decide that the signature for a d-wave nature of the gap parameter exists for such transport properties near the critical temperature.

“…The conventional theory can not reproduce the large TEP in the mixed state, similar to the high-T c cuprates. 48,49 The activation energy for the flux motion obtained from resistivity decreases exponentially with magnetic field, but the value obtained from TEP is nearly unchanged and larger, as shown in Fig. 4(c), also in contrast to conventional theory of flux motion.…”

We report thermal transport properties of KxFe2−ySe2 superconducting single crystal. Peak anomaly in thermal conductivity is observed at nearly, attributed to phonons. The thermoelectric power above Tc exhibits nearly linear behavior and could be described well by the carrier diffusion mechanism in a wide temperature range. The zero-temperature extrapolated thermoelectric power is smaller than the value in typical strongly correlated superconductors, implying large normalized Fermi temperature. These findings indicate that KxFe2−ySe2 is a weakly or intermediately correlated superconductor.

“…Although the origin of the sign reversal has not been clarified yet, 3-8 the mechanism seems not to be related to peculiarities of oxide high-T c materials, because the sign reversal has also been observed for low-T c materials. [9][10][11] In addition to the sign reversal near T c , a second sign reversal has been observed in Bi 2 Sr 2 CaCu 2 O x , 12 Tl 2 Ba 2 CaCu 2 O 8 , 4,13 ͑BiPb͒ 2 Sr 2 Ca 2 Cu 3 O d , 14 Tl 2 Ba 2 Ca 2 Cu 3 O d , 14 and HgBa 2 CaCu 2 O 6ϩd . 15 In these materials, the sign of the Hall effect is positive in the normal state and changes to negative near T c and becomes positive again at a lower temperature that depends on magnetic field.…”

Double sign reversal of the Hall effect in the mixed state ofYBa2Cu3O<

The Hall effect in a YBa 2 Cu 3 O x thin film was measured using high current densities of the order of 10 6 A/cm 2 , and the second sign reversal was observed clearly in the irreversible regime. The shape of the boundary between the positive and the negative Hall effect plotted on a B-T plane is similar to those of Bi-and Tl-based materials reported previously. Feigel'man et al.'s theory reproduces the experimental results qualitatively. ͓S0163-1829͑98͒04814-0͔
