Input-driven chaotic dynamics in vortex spin-torque oscillator
Yusuke Imai, Kohei Nakajima, Sumito Tsunegi +1
A new research topic in spintronics relating to the operation principles of brain-inspired computing is input-driven magnetization dynamics in nanomagnet. In this paper, the magnet…
Dzyaloshinskii-Moriya interaction in strongly spin-orbit-coupled systems: General formula and application to topological and Rashba materials
Yuto Hayakawa, Yusuke Imai, Hiroshi Kohno
We theoretically study the Dzyaloshinskii-Moriya interaction (DMI) mediated by band electrons with strong spin-orbit coupling (SOC). We first derive a general formula for the coeff…
Light-induced magnetization driven by interorbital charge motion in a spin-orbit assisted Mott insulator alpha-RuCl3
T. Amano, Y. Kawakami, H. Itoh +12
In a honeycomb-lattice spin-orbit assisted Mott insulator α-RuCl3, an ultrafast magnetization is induced by circularly polarized excitation below the Mott gap. Photo-carriers play…
Anomalous thermal Hall effect in the topological antiferromagnetic state
Kaori Sugii, Yusuke Imai, Masaaki Shimozawa +8
The anomalous Hall effect (AHE), a Hall signal occurring without an external magnetic field, is one of the most significant phenomena. However, understanding the AHE mechanism has…
Theory of Cross-correlated Electron-Magnon Transport Phenomena: Case of Magnetic Topological Insulator
Yusuke Imai, Hiroshi Kohno
We study transport phenomena cross-correlated among the heat and electric currents of magnons and Dirac electrons on the surface of ferromagnetic topological insulators. For a perp…
