摘要

软 X 射线反射率技术因其对元素和深度的敏感性，经常被用于研究薄膜中的磁化反转。使用该技术测量的特征磁滞回线取决于磁性材料的磁化方向和入射软 X 射线的偏振。在本说明中，我们讨论了软 X 射线反射率测量中的这些磁光效应。这些效应可用于探测由传统磁场刺激手段以外的刺激所驱动的磁化反转机制。为了证明这一点，我们介绍了对铁磁体（FM）/重金属（HM）异质结构中电流诱导磁化切换的研究。

Using magneto-optical effects in soft X-ray reflectivity to study current driven magnetization reversal

The soft X-ray reflectivity technique is frequently utilized for studying magnetization reversal in thin films due to its elemental and depth sensitivity. The characteristic hysteresis loops measured with this technique are dependent on both the magnetization direction in magnetic materials and the incident soft X-ray polarization. In this note, we have discussed these magneto-optical effects in soft X-ray reflectivity measurements. These effects can be exploited to probe magnetization reversal mechanisms driven by stimuli beyond conventional means of magnetic field. To demonstrate this, we have presented our investigations on current-induced magnetization switching in ferromagnet (FM)/heavy metal(HM) heterostructures.
