在室温下，CoPt/PMN-PT异质结构的磁性受到电场的控制。不仅剩余磁化强度，而且磁化率都对电场有明显的响应。在没有偏磁场的情况下，CoPt薄膜的剩磁表现出类似于电场开关的开关行为。由于电场引起的磁化率变化，这种异质结构中的磁化反转可以被电控制。
We demonstrate an obvious electric-field control of magnetic properties in CoPt/PMN-PT heterostructure at room temperature. Not only the remanent magnetization but also the coercivity exhibits an obvious response with the electric field. Without the aid of magnetic bias field, the remanent magnetization of the CoPt film shows an analogous on-off behavior with the electric field switching on and off alternatively. The magnetization reversal can be electrically controlled in this heterostructure due to the variation of coercivity caused by electric field.
