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…
Orthogonal Spin-Orbit Torque-Induced Deterministic Switching in NiO
Yixiao Qiao, Zhengde Xu, Zhuo Xu +2
The electrical switching of antiferromagnet (AFM) is very important for the development of ultrafast magnetic random-access memory (MRAM). This task becomes more difficult in antif…
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…
Deterministic Spin-Orbit Torque Switching of Mn3Sn with the Interplay between Spin Polarization and Kagome Plane
Zhengde Xu, Xue Zhang, Yixiao Qiao +3
Previous studies have demonstrated spin-orbit torque (SOT) switching of Mn3Sn where the spin polarization lies in the kagome plane (configuration I). However, the critical current…
Anomalous impact of thermal fluctuations on spintransfer torque induced ferrimagnetic switching
Zhengping Yuan, Jingwei Long, Zhengde Xu +6
The dynamics of a spin torque driven ferrimagnetic (FiM) system is investigated using the two-sublattice macrospin model. We demonstrate an ultrafast switching in the picosecond ra…
Spatially Nonuniform Oscillations in Ferrimagnets Based on an Atomistic Model
Xue Zhang, Baofang Cai, Jie Ren +5
The ferrimagnets, such as GdxFeCo(1-x), can produce ultrafast magnetic switching and oscillation due to the strong exchange field. The two-sublattices macrospin model has been wide…
