Field-tuned spin excitation spectrum of kπ skyrmion

Field-tuned spin excitation spectrum of kπ skyrmion

We study spin wave excitation modes of kπ skyrmion ( k  = 1, 2, 3) in a magnetic nanodot under an external magnetic field along the z direction using micromagnetic simulations based on the Landau–Lifshitz–Gilbert equation. We find that a transition of kπ skyrmion to other skyrmion-like structures ap...
