The temperature dependences of resistivities, rxx, transverse Hall resistivity rxy, Hall angle, magnetoresistance (MR), and magnetic susceptibility, x, will be measured. We discuss the superconducting origin and superconductivity mechanism of high temperature superconductors and iron-based superconductivity of copper oxide. Finally, we discuss and study the topological superconductivity further.高溫超導鐵基超導拓撲絕緣體拓撲界面high-Tc superconductingiron-based superconductortopological insulatortopological interface
