Oscillation modes of skyrmion strings in a ferromagnetic film
Eugene M. Chudnovsky, Dmitry A. Garanin
It is shown that a skyrmion string in a ferromagnetic film consisting of atomic layers exhibits flexural oscillations at eigenfrequencies $|ω_{m}|=(4J'S/\hbar)\sin^{2}[πm/(2N)]…
Barnett effect generated by a rotating electric field in a ferromagnetic film
Jorge F. Soriano, Eugene M. Chudnovsky
We investigate the space-time evolution of the magnetization induced in a 2D ferromagnetic island by a short pulse of a rotating electric field. The field generates elastic twists…
Massive dynamics of skyrmions in ferrimagnetic films
Dmitry A. Garanin, Eugene M. Chudnovsky
Deformations of skyrmions arising from the presence of more than one magnetic sublattice lead to their massive dynamics in ferrimagnets as compared to the massless dynamics in 2D f…
Skyrmion Cyclotron Resonance in Ferrimagnets
Eugene M. Chudnovsky, Dmitry A. Garanin
We show that a resonance due to gyroscopic motion of skyrmions, conceptually similar to the electron cyclotron resonance in metals, can be excited in a ferrimagnetic film by a spin…
Magnetization, excitations, and microwave power absorption in transition-metal/rare-earth ferrimagnets with disorder
D. A. Garanin, E. M. Chudnovsky
Efficient numerical routines are developed for numerical studies of the dependence of the equilibrium magnetic states, excitations, and microwave power absorption on temperature an…
Dislocation-induced magnetization reversal in a ferromagnetic film
Jorge F. Soriano, Eugene M. Chudnovsky
We demonstrate that moving edge dislocations can induce the reversal of magnetization in a ferromagnetic film due to the Barnett effect. The dynamics of magnetization is studied nu…
