Crystalline orientation of BiMnO3 thin films grown by rf-sputtering
BiMnO3 thin films were deposited by means of rf-sputtering onto [1 0 0] oriented SrTiO3 substrates. X-ray diffraction measurements revealed epitaxial growth with [0 0 1](m) orientation in the monoclinic structure representation, equivalent to the [1 1 1](pc) direction of the pseudocubic cationic lattice. This [0 0 1](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. (C) 2007 Elsevier B.V. All rights reserved.
