Magnetic interactions and spin excitations in van der Waals ferromagnet VI
Elijah Gordon, V. V. Mkhitaryan, Haijun Zhao +2
Using a combination of density functional theory (DFT) and spin-wave theory methods, we investigate the magnetic interactions and spin excitations in semiconducting VI. Exchang…
Self-consistently renormailzed spin-wave theory of layered ferromagnets on honeycomb lattice
Vagharsh Mkhitaryan, Liqin Ke
We develop a self-consistently renormalized spin-wave theory, within a mean-field approximation, for the two-dimensional Heisenberg ferromagnet with perpendicular easy-axis anisotr…
Defect-driven ferrimagnetism and hidden magnetization in MnBiTe
You Lai, Liqin Ke, Jiaqiang Yan +2
MnBiTe (MBT) materials are promising antiferromagnetic topological insulators where field driven ferromagnetism is predicted to cause a transition between axion insulator a…
X-ray spectra in magnetic van der Waals materials FeGeTe, CrI, and CrGeTe: a first-principles study
Y. Lee, V. N. Antonov, B. N. Harmon +1
Using density functional theory (DFT) methods, we have calculated X-ray absorption spectroscopy (XAS) and X-ray circular dichroism (XMCD) spectra in bulk and thin films of FeGe…
Electron correlation effects on exchange interactions and spin excitations in 2D van der Waals materials
Liqin Ke, Mikhail I. Katsnelson
Despite serious effort, the nature of the magnetic interactions and the role of electron-correlation effects in magnetic two-dimensional (2D) van der Waals materials remain elusive…
Deterministic strain-control of stability and current-induced motion of skyrmions in chiral magnets
Phuong-Vu Ong, Tae-Hoon Kim, Haijun Zhao +3
External magnetic field, temperature, and spin-polarized current are usually employed to create and control nanoscale vortex-like spin configurations such as magnetic skyrmions. Al…
