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)]…
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…
Integral Absorption of Microwave Power by Random-Anisotropy Magnets
E. M. Chudnovsky, D. A. Garanin
We study analytically and numerically on lattices containing spins, the integral absorption of microwaves by a random-anisotropy magnet, . It scales as $D^2_R/J…
Thermal fluctuations and longitudinal relaxation of single-domain magnetic particles at elevated temperatures
D. A. Garanin, O. Chubykalo-Fesenko
We present numerical and analytical results for the swiching times of magnetic nanoparticles with uniaxial anisotropy at elevated temperatures, including the vicinity of T_c. The c…
Saddle index properties, singular topology, and its relation to thermodynamical singularities for a phi^4 mean field model
D. A. Garanin, R. Schilling, A. Scala
We investigate the potential energy surface of a phi^4 model with infinite range interactions. All stationary points can be uniquely characterized by three real numbers $α_+, alpha…
