Microstructure and Dynamic Magnetic Properties of Thallium-Based Superconductors

Ac susceptibility study is one of the best methods in characterizing bulk superconductors. Four systems (A, B, C and D) of Thallium-based bulk superconductors were analyzed using this method. They were A = (TlO.8SCrO.lS) Sr2 (Ca1-xPrx)CU2O7,B=(Tl0.85Cr0.15)Sr2(Ca1-xNdx)Cu2O7, C=(Tl0.85Cr0.15)Sr2(Ca1...
