Epitaxial thin films of Bi2NiMnO6 were synthesized on SrTiO3 substrates by pulsed laser
deposition. The resulting film had the rock-salt-type arrangement of Ni2+ and Mn4+ ions in a
double-perovskite unit cell. The films clearly showed multiferroic properties, both ferromagnetic
behavior with a Curie temperature of about 100 K and ferroelectric behavior with a saturated
polarization of about 5 uC/cm2.
