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…
Interference of Instanton Trajectories in Quantum Tunneling for Small Particles of Real Antiferromagnets
B. A. Ivanov, V. E. Kireev
For a two-sublattice antiferromagnet the Lagrangian is constructed taking into account Berry phase whose form is matched to the quantum-mechanical Heisenberg Hamiltonian. Tunnel ef…
Instability Criteria for Vibrations of a Vortex Subject to a Gyro-force
B. A. Ivanov, A. Yu. Galkin
Here we study the instability of the vortex motion caused by vortex velocity non-monotonous dependence of the friction force in the presence of a gyro-force. We demonstrate that ev…
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…
Abrikosov vortex lattice nonlinear dynamics and its stability in the presence of weak defects
A. Yu. Galkin, B. A. Ivanov
Abrikosov vortex lattice dynamics in a superconductor with weak defects is studied taking into account gyroscopic (Hall) properties. It is demonstrated that interaction of the movi…
