Abstract
Since the discovery of superconductivity above 30 K by Bednorz and Müllerl and above 90 K by Wu et al.2, an ever increasing effort was made to investigate the physical properties of high-Tc ceramics. Most of the experiments report the resistivity drop and the diamagnetism as fundamental characteristics. The conclusions drawn from these effects do not, however, characterize a true physical property because of the effect of contacts and/or the superposition of simultaneous phenomena. The thermoelectric power (TEP) measurement seems to be one of the most sensitive tools to investigate the transport properties of high-Tc superconductors.
