Abstract
Thermoelectric powers S of La 2- x Sr x Cu 1- y M y O 4 (M=Zn and Ni) and YBa 2 Cu 3- y Zn y O 7-δ are measured for various values of x and y . A phenomenological description of the anomalous behavior of S is proposed, based on the electron damping which has an asymmetric form with respect to the chemical potential µ. The Zn doping seems to suppress the anomalous contribution of the electrons to various physical quantities, while the Ni-doping does not.Keywords
