Journal ArticleDOI
Writing and reading antiferromagnetic Mn2Au by Néel spin-orbit torques and large anisotropic magnetoresistance.
S. Yu. Bodnar,Libor Šmejkal,Libor Šmejkal,Libor Šmejkal,Ilja Turek,Tomas Jungwirth,Tomas Jungwirth,Olena Gomonay,Jairo Sinova,A. A. Sapozhnik,H. J. Elmers,Mathias Kläui,Martin Jourdan +12 more
TL;DR: Pulse current induced Néel vector switching in Mn2Au(001) epitaxial thin films is achieved, which is associated with a large magnetoresistive effect allowing simple read-out.
Journal ArticleDOI
Writing and Reading antiferromagnetic Mn$_2$Au: N\'eel spin-orbit torques and large anisotropic magnetoresistance
S. Yu. Bodnar,Libor Šmejkal,Ilja Turek,T. Jungwirth,Olena Gomonay,Jairo Sinova,A. A. Sapozhnik,H. J. Elmers,Mathias Kläui,Martin Jourdan +9 more
TL;DR: In this article, a spin-orbit torque was first experimentally demonstrated in a pioneering work using semimetallic CuMnAs and the symmetry of the torques agreed with theoretical predictions and a large read-out magnetoresistance effect of more than 6$~$\%$ was reproduced by ab initio transport calculations.
Journal ArticleDOI
Direct imaging of antiferromagnetic domains in Mn 2 Au manipulated by high magnetic fields
A. A. Sapozhnik,M. Filianina,S. Yu. Bodnar,A. Lamirand,M.-A. Mawass,Y. Skourski,H. J. Elmers,Hartmut Zabel,Mathias Kläui,Martin Jourdan +9 more
TL;DR: In this paper, the authors investigated spin-flop-induced changes of domain patterns in epitaxial thin films by x-ray magnetic linear dichroism photoemission electron microscopy (PEEM) using magnetic fields up to 70 T.
Journal ArticleDOI
Imaging of current induced Néel vector switching in antiferromagnetic Mn 2 Au
S. Yu. Bodnar,M. Filianina,S. P. Bommanaboyena,T. R. Forrest,Francesco Maccherozzi,A. A. Sapozhnik,Y. Skourski,Mathias Kläui,Martin Jourdan +8 more
TL;DR: In this paper, the effects of current induced N\'eel spin-orbit torques on the antiferromagnetic domain structure of epitaxial thin films were investigated by x-ray magnetic linear dichroism--photoemission electron microscopy.
Journal ArticleDOI
Néel Spin-Orbit Torque Driven Antiferromagnetic Resonance in Mn 2 Au Probed by Time-Domain THz Spectroscopy
Nilabha Bhattacharjee,A. A. Sapozhnik,S. Yu. Bodnar,V. Yu. Grigorev,Steinn Ymir Agustsson,J. Cao,Damir Dominko,Manuel Obergfell,Olena Gomonay,Jairo Sinova,Mathias Kläui,H. J. Elmers,Martin Jourdan,Jure Demsar +13 more
TL;DR: Electric manipulation of the Néel order parameter at high frequencies makes Mn_{2}Au a prime candidate for antiferromagnetic ultrafast memory applications.
