Numerical studies on antiferromagnetic skyrmions in nanodisks by means of a new quantum simulation approach

We find in simulations that when the nanodisk diameter is a few times longer than the DM length, multi-domains appear in the low temperature region. Then, introducing the uniaxial anisotropy normal to the disk plane in simulations can recover the single vortex. That is, such an anisotropy is able to induce and/or stabilize skyrmions in the disk plane. 273
