Thermodynamically self-consistent non-stochastic micromagnetic model for the ferromagnetic state
arXiv:1402.3487 · doi:10.1063/1.4900428
Abstract
In this work, a self-consistent thermodynamic approach to micromagnetism is presented. The magnetic degrees of freedom are modeled using the Landau-Lifshitz-Baryakhtar theory, that separates the different contributions to the magnetic damping, and thereby allows them to be coupled to the electron and phonon systems in a self-consistent way. We show that this model can quantitatively reproduce ultrafast magnetization dynamics in Nickel.
