Abstract

The temperature and DC magnetic field dependence of surface impedance (Z_s) of high temperature superconducting Bi(Pb)-Sr-Ca-Cu-O (BPSCCO) films on MgO substrate were measured at microwave frequency. At a low temperature, surface resistance (R_s) increases rapidly in the low DC magnetic field range and gradually in the high-field range. However, the surface reactance (X_s) also increases rapidly in low fields but hardly changes in high fields. At high temperature, R_s shows only a monotonic increase vs the field but X_s hardly changes.
