Manipulating chiral-spin transport with ferroelectric polarization
Xiaoxi Huang, Xianzhe Chen, Yuhang Li +28
A collective excitation of the spin structure in a magnetic insulator can transmit spin-angular momentum with negligible dissipation. This quantum of a spin wave, introduced more t…

Absence of cross-sublattice spin pumping and spin-transfer torques in collinear antiferromagnets
Junyu Tang, Ran Cheng
We resolve the debate over the existence and magnitude of cross-sublattice (CS) contributions to spin pumping and spin-transfer torques in a two-sublattice antiferromagnet connecte…

Lossless Spin-Orbit Torque in Antiferromagnetic Topological Insulator MnBiTe
Junyu Tang, Ran Cheng
We formulate and quantify the spin-orbit torque (SOT) in intrinsic antiferromagnetic topological insulator of a few septuple-layer thick, which exhibits conspicuou…
