Scattering mechanisms of a c-axis aligned (Bi,Pb)2Sr2Ca2Cu3Oy have been studied by a numerical analysis based on a model in which two scattering mechanisms, phonon-electron scattering and electron-electron scattering, are coexisting as the main cause of the thermal conductivity enhancement below the superconducting transition temperature, TC. We found a fairly good agreement between experimental results of temperature dependence and magnetic field dependence of the thermal conductivity and the coexisting model, as well as the model with electron-electron scattering (Proc.US-Japan WS on JC in high TC Oxide Superconductors (Oct.1995,Tsukuba): to be published), suggesting the coexistence of above mentioned two scattering mechanisms.
