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…
Melting and Freezing of a Skyrmion Lattice
Dmitry A. Garanin, Jorge F. Soriano, Eugene M. Chudnovsky
We report comprehensive Monte-Carlo studies of the melting of skyrmion lattices in systems of small, medium, and large sizes with the number of skyrmions ranging from to o…
Dynamics of Skyrmion Contraction and Expansion in a Magnetic Film
Eugene M. Chudnovsky
Contraction and expansion of skyrmions in ferromagnetic films are investigated. In centrosymmetric systems, the dynamics of a collapsing skyrmion is driven by dissipation. The coll…
Dynamics of the collapse of a ferromagnetic skyrmion in a centrosymmetric lattice
A. Derras-Chouk, E. M. Chudnovsky, D. A. Garanin
Time dependence of the size and chirality of a ferromagnetic skyrmion in a Heisenberg model with the magnetic field on a square lattice has been studied analytically and numericall…
Quantum States of a Skyrmion in a 2D Antiferromagnet
A. Derras-Chouk, E. M. Chudnovsky, D. A. Garanin
Quantum states of a skyrmion in a 2D antiferromagnetic lattice are obtained by quantizing the scaling parameter of Belavin-Polyakov model. Skyrmion classical collapse due to violat…
Conservation of Angular Momentum in the Elastic Medium with Spins
Dmitry A. Garanin, Eugene M. Chudnovsky
Exact conservation of the angular momentum is worked out for an elastic medium with spins. The intrinsic anharmonicity of the elastic theory is shown to be crucial for conserving t…
