Electrical generation and propagation of spin waves in antiferromagnetic thin films
Xinyi Xu, Yuriy G. Semenov, Ki Wook Kim
Electrical generation of THz spin waves is theoretically explored in an antiferromangetic nanostrip via the current-induced spin-orbit torque. The analysis based on micromagnetic s…
Thermal fluctuations in antiferromagnetic nanostructures
Yuriy G. Semenov, Xiniy Xu, Ki Wook Kim
A theoretical model is developed that can accurately analyze the effects of thermal fluctuations in antiferromagnetic (AFM) nano-particles. The approach is based on Fourier series…
Currentless reversal of Néel vector in antiferromagnets
Yuriy G. Semenov, Xi-Lai Li, Ki Wook Kim
The bias driven perpendicular magnetic anisotropy is a magneto-electric effect that can realize 90 magnetization rotation and even 180 flip along the easy axis i…
Conductance Discontinuity on the Surface of a Topological Insulator with Magnetic Electrodes
Xiaopeng Duan, Xi-Lai Li, Yuriy G. Semenov +1
Asymmetric electrical conductance is theoretically demonstrated on the surface of a topological insulator (TI) in the limit of infinitesimally small forward and reverse biases betw…
Spin Logic via Controlled Correlation in Nanomagnet-Dirac Fermion Heterostructures
Xiaopeng Duan, Yuriy G. Semenov, Ki Wook Kim

Tunable photo-galvanic effect on topological insulator surfaces via proximity interactions
Yuriy G. Semenov, Xiaodong Li, Ki Wook Kim
An unusual photo-galvanic effect is predicted on the topological insulator surface when its semi-metallic electronic spectrum is modified by an adjacent ferromagnet. The effect is…
