化学无序A1 CoPt单层中的电流感生磁化翻转
Current-induced magnetization switching in a chemically disordered A1 CoPt single layer
摘要:
我们报告的第一个示范的电流诱导磁化翻转在垂直磁化的A1 CoPt单层。我们表明,良好的垂直磁各向异性可以在很宽的组成范围内的A1 Co 1-xPtx单层,这使得制造垂直磁化的CoPt单层的组成梯度,打破结构的反转对称性。通过制备梯度CoPt单层,我们评估了SOT效率,并成功地实现了SOT诱导的磁化翻转。我们的研究提供了一种在不附加SOT源材料的情况下,在铁磁单层中实现电流感生磁化的方法。
英文摘要:
We report the first demonstration of the current-induced magnetization switching in a perpendicularly magnetized A1 CoPt single layer. We show that good perpendicular magnetic anisotropy can be obtained in a wide composition range of the A1 Co1-xPtx single layers, which allows to fabricate perpendicularly magnetized CoPt single layer with composition gradient to break the inversion symmetry of the structure. By fabricating the gradient CoPt single layer, we have evaluated the SOT efficiency and successfully realized the SOT-induced magnetization switching. Our study provides an approach to realize the current-induced magnetization in the ferromagnetic single layers without attaching SOT source materials.
