Band structure of CuMnAs probed by optical and photoemission spectroscopy
M. Veis, J. Minar, G. Steciuk +19
Tetragonal phase of CuMnAs progressively appears as one of the key materials for antiferromagnetic spintronics due to efficient current-induced spin-orbit torques whose existence c…
Spin-transport, spin-torque and memory in antiferromagnetic devices: Part of a collection of reviews on antiferromagnetic spintronics
J. Železný, P. Wadley, K. Olejník. A. Hoffmann +1
Ferromagnets are key materials for sensing and memory applications. In contrast, antiferromagnets that represent the more common form of magnetically ordered materials, have so far…
Spin Hall effect emerging from a chiral magnetic lattice without spin-orbit coupling
Yang Zhang, Jakub Zelezny, Yan Sun +2
The spin Hall effect (SHE), which converts a charge current into a transverse spin current, has long been believed to be a phenomenon induced by the spin--orbit coupling. Here, we…
Control of antiferromagnetic spin axis orientation in bilayer Fe/CuMnAs films
P. Wadley, K. W. Edmonds, M. R. Shahedkhah +10
Using x-ray magnetic circular and linear dichroism techniques, we demonstrate a collinear exchange coupling between an epitaxial antiferromagnet, tetragonal CuMnAs, and an Fe surfa…
Spin-polarized current in non-collinear antiferromagnets
Jakub Zelezny, Yang Zhang, Claudia Felser +1
Noncollinear antiferromagnets, such as MnSn and MnIr, were recently shown to be analogous to ferromagnets in that they have a large anomalous Hall effect. Here we show that…
