Abstract

By using solid state reaction method, Fe doped (Bi,Pb)2Sr2Ca2 Cu2Oy high temperature superconductor samples were synthesized. The phase purity and the morphology of samples were obtained from XRD and SEM measurements. The temperature dependencies of real and imaginary parts of AC susceptibility were performed by using different values of AC field amplitude. Temperature dependencies of the irreversibility line for intergranular flux motion were obtained..

Keywords
