Spin dynamics of anisotropic azimuthal modes in heterogeneous magnetic nanodisks
Huirong Zhao, Zhengyun Lei, Ruifang Wang
It is well known that azimuthal spin wave modes of magnetic vortex state in permalloy nanodisks have circular symmetry. Intuitively, magnetic materials having magnetocrystalline an…

Unusual spin-wave dynamics in core-shell magnetic nanodisks
Huirong Zhao, Ruifang Wang
We investigated the spin dynamics of a vortex state in a core-shell magnetic nanodisk driven by an oscillating field applied perpendicular to the disk plane by means of micromagnet…
