Abstract

Multiferroic Gd, Mn co-doped BiFeO₃ (BFO)/CoFe₂O₄ (CFO) heterostructure film has been deposited by the chemical solution deposition on a FTO/glass substrate. The influence of CoFe₂O₄ layer and (Gd, Mn) co-substitution on multiferroic properties of the heterostructure film was investigated. The XRD and SEM results reveal that the well double-layer heterostructure film is obtained. It is found that (Gd, Mn) co-substitution induces a structural transformation in the BFO layer. Compared with BFO/CFO, (Gd, Mn)-BFO/CFO film presents highly enhanced ferroelectric properties and dramatically reduced leakage current. In addition, the ferromagnetism of the (Gd, Mn)-BFO/CFO is dominated by the CFO layer, meanwhile the (Gd, Mn)-BFO layer also promotes the ferromagnetic properties of the heterostructure. The obtained Gd, Mn-BFO/CFO heterostructure film simultaneously exhibits remarkable ferroelectricity (2P_r ∼ 165 μC/cm²) and ferromagnetism (M_r ∼ 55.0 emu/cm³) at room temperature.
