Investigation of Sub-configurations Reveals Stable Spin-Orbit Torque Switching Polarity in Polycrystalline Mn3Sn
Boyu Zhao, Zhengde Xu, Xue Zhang +3
Previous studies have demonstrated the switching of octupole moment in Mn3Sn driven by spin-orbit torque (SOT). However, they have not accounted for the polycrystalline nature of t…
Anomalous switching pattern in the ferrimagnetic memory cell
Zhuo Xu, Zhengping Yuan, Xue Zhang +4
Replacing the ferromagnet with ferrimagnet (FiM) in the magnetic tunnel junction (MTJ) allows faster magnetization switching in picoseconds. The operation of a memory cell that con…
Spin-Orbit Torque Driven Chiral Domain Wall Motion in Mn3Sn
Zhengde Xu, Yue Zhou, Xue Zhang +3
Noncollinear chiral antiferromagnets, such as Mn3X (X = Sn, Ge), have garnered significant interest in spintronics due to their topologically protected Weyl nodes and large momentu…
Revisiting the Analytical Solution of Spin-Orbit Torque Switched Nanoscale Perpendicular Ferromagnet
Xue Zhang, Zhengde Xu, Zhifeng Zhu
The scaling of magnetic memory into nanometer size calls for a theoretical model to accurately predict the switching current. Previous models show large discrepancy with experiment…
