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.PACS Nos.: 76.20.+q, 72.25.Ba
