We have grown epitaxial thin films of multiferroic BiMnO3 using pulsed laser deposition. The films were grown on SrTiO3 001 substrates by ablating a Bi-rich target. Using x-ray diffraction, we confirmed that the films were epitaxial and the stoichiometry of the films was confirmed using Auger electron spectroscopy. The films have a ferromagnetic Curie temperature (TC) of 85 +/- 65 K and a saturation magnetization of 1 mu(B)/Mn. The electric polarization as a function of electric field (P-E) was measured using an interdigital capacitance geometry. The P-E plot shows a clear hysteresis that confirms the multiferroic nature of the thin films. (C) 2011 American Institute of Physics. [doi: 10.1063/1.3561860]
