最近，研究人员已经开发了光伏（PV）控制的磁性，以提供一种新的方式操纵自旋态的能量有效的方式，其中磁操纵的能力是至关重要的。在这里，我们建立了一个光伏异质结构Pt/PV/ZnO/Co/Si，以实现太阳光的磁性控制，其中ZnO层的引入，以提高电子输运以及界面的光电磁可调谐性。与没有ZnO层的光伏异质结（245 Oe）相比，在太阳光照射下，最佳ZnO插入层获得了更大的铁磁共振位移（1149 Oe）和饱和磁化强度降低（12.7%）。这些结果证明了ZnO层在优化磁操纵和打开未来光伏自旋电子学的大门方面起着关键作用。
Recently, researchers have developed photovoltaic (PV) control of magnetism to provide a new way of manipulating spin states in an energy-effective manner, where the capability of magnetism manipulation is crucial. Here, we established a PV heterostructure of Pt/PV/ZnO/Co/Si to realize sunlight control of magnetism, where the ZnO layer is introduced to enhance the electron transportation as well as the interfacial optical-electromagnetic tunability. Compared to the PV heterostructure without the ZnO layer (245 Oe), a much greater ferromagnetic resonance shift (1149 Oe) and a saturated magnetization reduction (12.7%) were obtained with the optimal ZnO inserting layer under sunlight illumination. These results prove that the ZnO layer plays a key role in optimizing magnetic manipulation and opening a door toward PV spintronics in the future.
