Abstract
Multiferroic (Bi1-xEux)(Fe1-xMnx)O3 (BEFM-x, x=0.00, 0.02, 0.04, 0.06, 0.08, and 0.10) thin films were prepared on Pt(111)/Ti/SiO2/Si(100) substrates by using a chemical solution deposition method. Compared to the pure BiFeO3 thin film, improved ferroelectric property and reduced leakage current density were observed in the co-doped BEFM-x thin films. Among them, the BEFM-0.08 thin film capacitor showed the best properties. The values of remnant polarization (2Pr) and coercive electric field (2Ec) were 93 μC/cm2 and 531 kV/cm at an applied electric field of 932 kV/cm, respectively. The leakage current density of the BEFM-0.08 thin film capacitor was 2.5×10-5 A/cm2 at 100 kV/cm.
