Abstract
Superconducting samples of YBa2(Cu1-xMnx)(3)O7-delta with x = 0, 0.01, 0.01 5, 0.02, 0.025, 0.035, and 0.05 have been prepared and the temperature vari ation of the Seebeck coefficient, S(T), has been measured over a temperatur e region of 77 to 250 K. The observed features of the results are analyzed in terms of the metallic diffusion model, the Nagaosa-Lee model, and a narr ow band model. The physical parameters obtained are discussed.
