英文摘要: The Ag/BiFeO3 thin films were prepared on ITO/glass substrate by in situ sol–gel method. The morphology and formation of the perovskite phase and Ag nanoparticles (NPs) were studied by XRD, SEM, and UV–Vis spectra. The doping of Ag+ ions and the formation of defects were analyzed by XPS measurement. The dielectric and magnetic properties were measured by impedance analyzer and magnetic property measurement system. Results showed that a few Ag+ ions (<7%) were doped into the bismuth ferrite lattice to substitute Bi. In addition, most of the Ag+ ions were reduced to Ag NPs in BiFeO3 thin films and the Ag NPs/BiFeO3 composite thin film was formed. The Ag+ ions doping was beneficial for not only the formation of...
