Abstract

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 (T_C) of 85 ± 5 K and a saturation magnetization of 1 _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.
