Bi1-x Er (x) FeO3 (BE (x) FO, x = 0.07-0.12) films have been deposited on fluorine-doped SnO2 (FTO) substrates by a chemical solution deposition method (CSD). The structure and multiferroic properties were investigated. The results indicate that there is a structural transition from the typical rhombohedral-R3c:H (BiFeO3) to two-phase coexistence of rhombohedral-R3c:H and rhombohedral-R3m:R (BE (x) FO). The abundant Fe2+ are observed in BE (x) FO, which induces the larger leakage current. The BE0.09FO shows the ferroelectric switching current of 1.42 x 10(-2) A and the enhanced magnetization (saturation magnetization M (s) similar to 2.60 emu/cm(3)). From the investigation, the BE (x) FO films will be expected to show the great multiferroic properties after reducing the leakage current.
