摘要

Pt/Tm3Fe5O12（TmIG）双层层内的自旋轨道力矩为操纵 TmIG 的磁化提供了一种便捷的方法。然而，TmIG 的实际应用却因切换过程中存在外部磁场而受到阻碍。在这里，我们展示了在沧桑基底上的 Pt/TmIG 双层中的无磁场磁化切换，其对 TmIG 的垂直磁各向异性（PMA）的牺牲最小。在倾斜 PMA 的帮助下，在没有外场的情况下实现了可逆的垂直磁化切换。我们的研究结果为在 Pt/TmIG 双层中实现无磁场垂直磁化切换提供了另一种解决方案，从而促进了基于 SOT 的新兴器件的发展。

Field-free magnetization switching with full scale in Pt/Tm3Fe5O12 bilayer on vicinal substrate

The spin–orbit torques within a Pt/Tm3Fe5O12 (TmIG) bilayer offer an expedient method for manipulating the magnetization of TmIG. However, the practical application of TmIG is hindered by the presence of an external field during switching. Here, we demonstrate field-free magnetization switching in Pt/TmIG bilayer on a vicinal substrate with minimal sacrifice to the perpendicular magnetic anisotropy (PMA) of TmIG. With the assistance of tilt PMA, reversible perpendicular magnetization switching is realized in the absence of an external field. Our results offer an alternative solution for achieving field-free perpendicular magnetization switching in a Pt/TmIG bilayer, thereby fostering the advancement of emerging SOT-based devices.
