Summary:Ferroelectric properties of Dy and Mn codoped BiFeO..., (...)(...)O... (BDFM-x, x = 0, 0.02, 0.04, 0.06, 0.08, and 0.10), thin films were investigated. Improved ferroelectric properties were observed in the codoped thin film capacitors. Among them, BDFM-0.08 thin film capacitor exhibited the best properties. The remnant polarization (2P...) and coercive electric field (2E...) of the BDFM-0.08 thin film capacitor were 96 ...C/cm... and 695 kV/cm at an applied electric field of 1061 kV/cm, respectively. The leakage current density of the BDFM-0.08 thin film capacitor was 8.3 x 10... A/cm... at 400 kV/cm. (ProQuest: ... denotes formulae/symbols omitted.)
