研究了在SrTiO 3和Nb-SrTiO 3（001）衬底上生长的La 2CoMnO 6（LcmO）-ZnO纳米复合薄膜。薄膜以自组装外延垂直排列结构的形式生长。我们发现，在120 K，施加在整个纳米复合材料的电场可逆地改变磁性能的LcmO。这种效应与电荷介导的磁场和电场之间的耦合是一致的，这种耦合可以由离子价态的变化引起。
La2CoMnO6 (LcmO)-ZnO nanocomposite thin films grown on SrTiO3 and Nb-SrTiO3 (001) are investigated. The films grow in the form of self-assembled epitaxial vertically aligned structures. We show that, at 120 K, an electric field applied across the nanocomposite reversibly alters magnetic properties of LcmO. The effect is consistent with charge-mediated coupling between magnetism and an electric field that can be induced by changes in ion valences.
