Regular and in-plane skyrmions and antiskyrmions from boundary instabilities
Shane Sandhoefner, Aldo Raeliarijaona, Rabindra Nepal +2
We formulate a theory of skyrmion and antiskyrmion generation using magnetic field and charge current pulses. We show that the topological defect can be created at an edge of a sys…
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…
Stabilization and control of Majorana bound states with elongated skyrmions
Utkan Güngördü, Shane Sandhoefner, Alexey A. Kovalev
We show that elongated magnetic skyrmions can host Majorana bound states in a proximity-coupled two-dimensional electron gas sandwiched between a chiral magnet and an -wave supe…
