Abstract We report the pure voltage manipulation of desired in-plane magnetization orientation of the nanomagnets in Ni/PMN-PT multiferroic heterostructure and systemically studies the effect of localized stress on the magnetization orientation by magnetic force microscope. Referable analysis about the dynamic magnetization process of the nanomagnet are provided by micromagnetic simulation. Both the experiments and simulations have proved that the 180 degrees switching of the nanomagnets can be induced without strict requirements of the voltage waveform. The results can be effectively applied to electrical induced logic writing of low-energy-consumption spintronic devices.

多铁异质结构中所需磁化方向的电压操纵

摘要 我们报告了 Ni/PMN-PT 多铁异质结构中纳米磁铁所需面内磁化取向的纯电压操纵，并通过磁力显微镜系统地研究了局部应力对磁化取向的影响。微磁模拟为纳米磁体的动态磁化过程提供了参考分析。实验和仿真都证明了纳米磁体的180度开关可以在不严格要求电压波形的情况下进行感应。结果可以有效地应用于低能耗自旋电子器件的电感应逻辑写入。
