Abstract

We have measured the thermoelectric power S and resistivity (formula presented) of (formula presented) S is positive and increases linearly with temperature above the superconducting transition temperature (formula presented) Deviations from the linear dependence appear at higher temperature, (formula presented) (formula presented) and (formula presented) both decrease with Al doping whereas the slope of (formula presented) in the linear range increases with the Al content. The data are discussed in terms of doping-induced changes of the Fermi surface and the density of states at the Fermi level.
