Peter Wadley,B. Howells,Jakub Zelezny,C. Andrews,V. Hills,R. P. Campion,Vít Novák,Frank Freimuth,Yuriy Mokrousov,A. W. Rushforth,K. W. Edmonds,B. L. Gallagher,Tomas Jungwirth +12 more
TL;DR: In this paper, the equivalence of antiferromagnets and ferromagnetic spintronics for effects that are an even function of the magnetic moment has been demonstrated based on even-in-moment relativistic transport phenomena.
Journal ArticleDOI
Imaging Current-Induced Switching of Antiferromagnetic Domains in CuMnAs.

TL;DR: Using x-ray magnetic linear dichroism microscopy, it is shown that staggered effective fields generated by electrical current can induce modification of the antiferromagnetic domain structure in microdevices fabricated from a tetragonal CuMnAs thin film.
Journal ArticleDOI
Optical determination of the Néel vector in a CuMnAs thin-film antiferromagnet

TL;DR: In this paper, a femtosecond pump-probe magneto-optical experiment based on magnetic linear dichroism was used to determine the Neel vector orientation in a thin film of antiferromagnetic CuMnAs.
Journal ArticleDOI

Peter Wadley,V. Hills,M. R. Shahedkhah,K. W. Edmonds,R. P. Campion,Václav Novák,Bachir Ouladdiaf,Dmitry D. Khalyavin,Sean Langridge,V. Saidl,P. Nemec,A. W. Rushforth,B. L. Gallagher,Sarnjeet S. Dhesi,Francesco Maccherozzi,J. Železný,Tomas Jungwirth +16 more
TL;DR: Using a combination of neutron diffraction and x-ray magnetic linear dichroism, the spin axis and magnetic structure in tetragonal CuMnAs is determined, and the presence of an interfacial uniaxial magnetic anisotropy is revealed.
