Dynamics of topological solitons in two-dimensional ferromagnets
Denis D. Sheka, Christian Schuster, Boris A. Ivanov +1
Dynamical topological solitons are studied in classical two-dimensional Heisenberg easy-axis ferromagnets. The properties of such solitons are treated both analytically in the cont…
Vortex motion in a finite-size easy-plane ferromagnet and application to a nanodot
Denis D. Sheka, Juan P. Zagorodny, Jean-Guy Caputo +2
We study the motion of a non-planar vortex in a circular easy-plane ferromagnet, which imitates a magnetic nanodot. Analysis was done using numerical simulations and a new collecti…
Amplitudes for magnon scattering by vortices in two-dimensional weakly easy-plane ferromagnets
Denis D. Sheka, Ivan A. Yastremsky, Boris A. Ivanov +2
We study magnon modes in the presence of a vortex in a circular easy-plane ferromagnet. The problem of vortex-magnon scattering is investigated for partial modes with different val…
Dynamics of Vortices in Two-Dimensional Magnets
F. G. Mertens, A. R. Bishop
Theories, simulations and experiments on vortex dynamics in quasi-two-dimensional magnetic materials are reviewed. These materials can be modelled by the classical two-dimensional…
Hierarchy of equations of motion for nonlinear coherent excitations applied to magnetic vortices
F. G. Mertens, H. -J. Schnitzer, A. R. Bishop
Starting from a travelling wave ansatz we show successively that the shape of a nonlinear excitation generally depends also on the 1st, 2nd, ... time derivative of the position X o…
Vortices in Quantum Spin Systems
John Schliemann, Franz G. Mertens
We examine spin vortices in ferromagnetic quantum Heisenberg models with planar anisotropy on two-dimensional lattices. The symmetry properties and the time evolution of vortices b…
