Current-induced fragmentation of antiferromagnetic domains
M. S. Wörnle, P. Welter, Z. Kašpar +7
Electrical and optical pulsing allow for manipulating the order parameter and magnetoresistance of antiferromagnets, opening novel prospects for digital and analog data storage in…
Molecular beam epitaxy of CuMnAs
Filip Krizek, Zdeněk Kašpar, Aliaksei Vetushka +13
We present a detailed study of the growth of the tetragonal polymorph of antiferromagnetic CuMnAs by the molecular beam epitaxy technique. We explore the parameter space of growth…
Spin flop and crystalline anisotropic magnetoresistance in CuMnAs
M. Wang, C. Andrews, S. Reimers +20
Recent research works have shown that the magnetic order in some antiferromagnetic materials can be manipulated and detected electrically, due to two physical mechanisms: Neel-orde…
Quenching of an antiferromagnet into high resistivity states using electrical or ultrashort optical pulses
Zdeněk Kašpar, Miloslav Surýnek, Jan Zubáč +16
Ultra-fast dynamics, insensitivity to external magnetic fields, or absence of magnetic stray fields are examples of properties that make antiferromagnets of potential use in the de…
Gating effects in antiferromagnetic CuMnAs
M. J. Grzybowski, P. Wadley, K. W. Edmonds +6
Antiferromagnets (AFs) attract much attention due to potential applications in spintronics. Both the electric current and the electric field are considered as tools suitable to con…
Emerging edge states on the surface of the epitaxial semimetal CuMnAs thin film
Giang D. Nguyen, Krishna Pitike, Peter Wadley +4
Epitaxial thin films of CuMnAs have recently attracted attention due to their potential to host relativistic antiferromagnetic spintronics and exotic topological physics. Here we r…
