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.

邻位基底上 Pt/Tm3Fe5O12 双层的满量程无场磁化开关

_{Pt/Tm 3} Fe ₅ O ₁₂ (TmIG)双层内的自旋轨道扭矩为操纵TmIG的磁化强度提供了一种便捷的方法。然而，TmIG 的实际应用受到开关过程中外部场的存在的阻碍。在这里，我们展示了邻位基板上 Pt/TmIG 双层中的无场磁化开关，对 TmIG 的垂直磁各向异性 (PMA) 的牺牲最小。借助倾斜PMA，在没有外场的情况下实现了可逆垂直磁化翻转。我们的研究结果为在 Pt/TmIG 双层中实现无场垂直磁化转换提供了一种替代解决方案，从而促进了新兴 SOT 器件的进步。
