High bosonic Bott index and transport of multi-band topological magnons
Kai Tao Huang, X. S Wang
Magnons are bosonic quasiparticles in magnetically ordered systems. Bosonic Bott index has been affirmed as a real-space topological invariant for a two-band ferromagnetic model. I…

Stabilization and dynamics of magnetic antivortices in a nanodisk with anisotropic Dzyaloshinskii-Moriya interaction
Xin Hu, X. S. Wang, Zhenyu Wang
We theoretically investigate the antivortex stabilized by anisotropic Dzyaloshinskii-Moriya interaction (DMI) in nanodisks. It is remarkably found that the antivortex remains stabl…

Field-free ultrafast magnetization reversal of a nanodevice by a chirped current pulse via spin-orbit torque
Y. D. Liu, M. T. Islam, T. Min +2
We investigated the magnetization reversal of a perpendicularly magnetized nanodevice using a chirped current pulse (CCP) via spin-orbit torques (SOT). Our findings demonstrate tha…
