A magnetization equation for non-equilibrium spin systems
arXiv:0711.1576 · doi:10.1139/P07-187
Abstract
A magnetization equation for a system of spins evolving non-adiabatically and out of equilibrium is derived without specifying the internal interactions. For relaxation processes, this equation provides a general form of magnetization damping. A special case of the spin-spin exchange interaction is considered.
