Magnetoelectric control of topological phases in graphene
Hiroyuki Takenaka, Shane Sandhoefner, Alexey A. Kovalev +1
Topological antiferromagnetic (AFM) spintronics is an emerging field of research, which involves the topological electronic states coupled to the AFM order parameter known as the N…

Intrinsic spin Nernst effect of magnons in a noncollinear antiferromagnet
Bo Li, Shane Sandhoefner, Alexey A. Kovalev
We investigate the intrinsic magnon spin current in a noncollinear antiferromagnetic insulator. We introduce a definition of the magnon spin current in a noncollinear antiferromagn…

Skyrmions and antiskyrmions in quasi-two-dimensional magnets
Alexey A. Kovalev, Shane Sandhoefner
A stable skyrmion, representing the smallest realizable magnetic texture, could be an ideal element for ultra-dense magnetic memories. Here, we review recent progress in the field…
