由自旋转移开关(STS)驱动的新型磁光空间光调制器(SLM)有望实现超高分辨率的SLM。然而，它的克尔旋转角是不够的，需要使用极克尔来改进。Gd-Fe薄膜具有很大的MO效应，被称为MO盘材料。在本研究中，我们应用了一层Gd-Fe层和多层Co/Ni层的复合薄膜作为CPP-GMR器件的自由层。我们制作了具有垂直磁各向异性的CPP-GMR器件，并使用透明顶电极成功地实现了STS驱动的磁光观测。
A new magneto-optical (MO) spatial light modulator (SLM) driven by spin transfer switching (STS) promises the realization of an ultra-high resolution SLM. However, its Kerr rotation angle was inadequate and required improvement using polar Kerr. Gd-Fe film, known as a material for MO disks, has a large MO effect. In this study, we applied a composite film with a Gd-Fe layer and multiple Co/Ni layers for a free layer of a CPP-GMR device. We fabricated a CPP-GMR device with perpendicular magnetic anisotropy and succeeded in magneto-optical observations driven by STS using a transparent top electrode.
