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…
Unidirectional Spin Hall Magnetoresistance in Antiferromagnetic Heterostructures
Yang Cheng, Junyu Tang, Justin J. Michel +4
Unidirectional spin Hall magnetoresistance (USMR) has been widely reported in the heavy metal / ferromagnet (HM/FM) bilayer systems. We observe the USMR in the Pt/α-Fe2O3 bilayers…
Voltage-driven exchange resonance achieving 100\% mechanical efficiency
Junyu Tang, Ran Cheng
Magnetic resonances driven by current-induced torques are crucial tools to study magnetic materials but are very limited in frequency and mechanical efficiency. We propose an alter…
