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…
A Perspective on Magnon Spin Nernst Effect in Antiferromagnets
Hantao Zhang, Ran Cheng
Magnon excitations in antiferromagnetic materials and their physical implications enable novel device concepts not available in ferromagnets, emerging as a new area of active resea…
Quantifying Spin-Orbit Torques in Antiferromagnet/Heavy Metal Heterostructures
Egecan Cogulu, Hantao Zhang, Nahuel N. Statuto +4
The effect of spin currents on the magnetic order of insulating antiferromagnets (AFMs) is of fundamental interest and can enable new applications. Toward this goal, characterizing…
Theory of Harmonic Hall Responses of Spin-Torque Driven Antiferromagnets
Hantao Zhang, Ran Cheng
Harmonic analysis is a powerful tool to characterize and quantify current-induced torques acting on magnetic materials, but so far it remains an open question in studying antiferro…
