- •
Mn, Co co-doped BFO/CFO double-layer film has been successfully deposited by CSD.
- •
Effect of co-doping on structure, multiferroic properties of films was studied.
- •
Mn, Co–BFO/CFO shows superior multiferroic Pr ∼ 123 渭C/cm2 and Mr ∼ 67 emu/cm3.
- •
The reduction of Fe2+ and the existence of high valence Fe were confirmed by XPS.
