Description
Summary:(BiNd0.05)(Fe0.97Mn0.03)O3 (BNFM)/Pt/CoFe2O4 (CFO) layered thin film was fabricated on (100) SrTiO3 substrate by pulsed laser deposition. BNFM, Pt, and CFO layers were epitaxially grown on the substrate. Almost no increase of leakage current due to the formation of heteroepitaxial structure was found, and well-saturated hysteresis loops in the polarization vs electric field and magnetization vs magnetic field curves coexist at room temperature. The remnant polarization and remnant magnetization values were 55 mu C/cm2, and 70-145mA/m, respectively.
