Abstract

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 × 10−2 A and the enhanced magnetization (saturation magnetization M s  ~ 2.60 emu/cm3). From the investigation, the BE x FO films will be expected to show the great multiferroic properties after reducing the leakage current.
