采用脉冲激光沉积法在SrTiO3衬底上制备了Bi2NiMnO6外延薄膜。所得薄膜具有双钙钛矿单元电池中的Ni2+和Mn4+离子的岩盐型排列。薄膜明显地表现出多铁性，即居里温度约为100 K的铁磁行为和饱和极化约为5μC scincm 2的铁电行为。
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 100K and ferroelectric behavior with a saturated polarization of about 5μC∕cm2.
