摘要

BiMnO_3 thin films were deposited by means of rf-sputtering onto [100] oriented SrTiO_3 substrates. X-ray diffraction measurements revealed epitaxial growth with [001]_m orientation in the monoclinic structure representation, equivalent to the [111] direction of the pseudocubic cationic lattice. This [001]_m orientation was obtained in a wide deposition parameters range. Preliminary magnetization measurements suggest that these films do not present ferromagnetism below the bulk Curie temperature, T_C = 105 K.
