Abstract

In this paper, we present temperature dependent electrical conductivity ρ (T), thermal conductivity κ (T) and thermoelectric power S (T) for co-doped superconducting compounds Y 0.95Pr0.5Ba2(Cu1-xM x)3O7-δ(M=Fe,Mn,Zn and Ni). The XRD patterns confirm that all the samples are single phased. Pristine Y Ba2Cu3O7-δ depicts a pronounced hump-like structure in κ (T) below its transition temperature. With Pr-doping, a reduction in the peak height of the hump is observed. It is found that the hump structure is further suppressed with transition metal co-doping, and is viewed in terms of the phonon scattering with defect structure, electrons and phonons. S (T) data depicting a sign reversal with co-doping, has been analyzed in the framework of a narrow band model.
