Antiferromagnetic half-skyrmions electrically generated and controlled at room temperature
O. J. Amin, S. F. Poole, S. Reimers +12
Topologically protected magnetic textures, such as skyrmions, half-skyrmions (merons) and their antiparticles, constitute tiny whirls in the magnetic order. They are promising cand…
Magneto-Seebeck microscopy of domain switching in collinear antiferromagnet CuMnAs
Tomas Janda, Joao Godinho, Tomas Ostatnicky +23
Antiferromagnets offer spintronic device characteristics unparalleled in ferromagnets owing to their lack of stray fields, THz spin dynamics, and rich materials landscape. Microsco…
Imaging current-induced switching of antiferromagnetic domains in CuMnAs
M. J. Grzybowski, P. Wadley, K. W. Edmonds +9
The magnetic order in antiferromagnetic (AF) materials is hard to control with external magnetic fields. However, recent advances in detecting and manipulating AF order electricall…
Electrical switching of an antiferromagnet
Peter Wadley, Bryn Howells, Jakub Zelezny +10
Louis Neel pointed out in his Nobel lecture that while abundant and interesting from a theoretical viewpoint, antiferromagnets did not seem to have any applications. Indeed, the al…
Element-resolved orbital polarization in (III,Mn)As ferromagnetic semiconductors from edge x-ray magnetic circular dichroism
P. Wadley, A. A. Freeman, K. W. Edmonds +9
Using x-ray magnetic circular dichroism (XMCD), we determine the element-specific character and polarization of unoccupied states near the Fermi level in (Ga,Mn)As and (In,Ga,Mn)As…
