Abstract

The (Na_0.5Bi_0.5)_0.98Ce_0.02(Ti_0.99Fe_0.01)O₃–BiFe_0.95Mn_0.05O₃ (NBTCeFe–BFOMn) solid-solution thin film was fabricated on LaNiO₃/Si substrate by metal organic decomposition. The leakage current density of NBTCeFe–BFOMn film at 400 kV/cm was reduced by approximately two orders of magnitude by reducing the density of oxygen vacancies and forming the defect complexes, compared with Na_0.5Bi_0.5TiO₃ film. Much enhanced ferroelectric and magnetic properties were achieved in NBTCeFe– BFOMn film with a remanent polarization of 32.6 μC/cm² and a saturated magnetization of 6.2 emu/cm³. The dielectric constant–voltage curve coincides well with the polarization–electric field loop.
