铁磁体中磁化翻转的电控制对于未来的自旋电子学应用是高度期望的。在这里，我们报告的混合压电（PZT）/铁磁（Co2 FeAl）设备中的铁磁层中的平面霍尔电压仅由压电电压调谐。平面霍尔电压的变化与压电电压下平面内90°的磁化翻转有关。在无外磁场的情况下，基于压控Co2 FeAl平面霍尔效应器件，实现了室温磁性非门和或非门。我们的演示可能会导致使用铁磁材料实现信息存储和处理。
The electrical control of the magnetization switching in ferromagnets is highly desired for future spintronic applications. Here we report on hybrid piezoelectric (PZT)/ferromagnetic (Co2FeAl) devices in which the planar Hall voltage in the ferromagnetic layer is tuned solely by piezo voltages. The change of planar Hall voltage is associated with magnetization switching through 90° in the plane under piezo voltages. Room temperature magnetic NOT and NOR gates are demonstrated based on the piezo voltage controlled Co2FeAl planar Hall effect devices without the external magnetic field. Our demonstration may lead to the realization of both information storage and processing using ferromagnetic materials.
