Theroy of magnetic inertial dynamics in two-sublattice ferromagnets

چکیده
The magnetic inertial dynamics have been investigated for one sublattice ferromagnets. Here, we develop the magnetization in two-sublattice ferromagnets including intra- and inter-sublattice dynamics. First, derive susceptibility of such a ferromagnet. Next, by finding poles susceptibility, calculate precession nutation resonance frequencies. Our results suggest that while frequencies show decreasing behavior with increasing intra-sublattice relaxation time, effect is contrasting.

متن کاملDynamics of topological solitons in two-dimensional ferromagnets
Dynamical topological solitons are studied in classical two–dimensional Heisenberg easy–axis ferromagnets. The properties of such solitons are treated both analytically in the continuum limit and numerically by spin dynamics simulations of the discrete system. Excitation of internal mode causes orbital motion. This is confirmed by simulations. Submitted to: J. Phys.: Condens. Matter PACS number...
متن کاملPerpendicular magnetic anisotropy of two-dimensional Rashba ferromagnets.
We compute the magnetocrystalline anisotropy energy within two-dimensional Rashba models. For a ferromagnetic free-electron Rashba model, the magnetic anisotropy is exactly zero regardless of the strength of the Rashba coupling, unless only the lowest band is occupied. For this latter case, the model predicts in-plane anisotropy. For a more realistic Rashba model with finite band width, the mag...
متن کاملCritical Dynamics of Ferromagnets
The crossover in the dynamics from isotropic to dipolar critical behaviour has been a matter of debate over many years. We review a mode coupling theory for dipolar ferromagnets which gives a unified explanation of the seemingly contradictory experimental situation. The shape functions, the scaling functions for the damping coefficients and the precise position of the crossover are computed. Be...
