摘要：
Ag addition to YBa2Cu3O7-x superconducting films prepared using electrophoretic deposition on Cu substrates was investigated. The electrical characteristics of the films, such as zero-resistance temperature (T(c)), critical current density (J(c)), and resistivity at room temperature (rho) were greatly improved by Ag doping. The T(c) of 94 K was attained with the electrophoretic Ag-doped film on Cu substrate. By doping with Ag, the grain growth was enhanced but no shift in YBa2Cu3O7-x peaks was observed in X-ray diffraction patterns. From the electron probe microanalysis of the sample cross section, the doped Ag was found to exist in the region devoid of YBa2Cu3O7-x
