Abstract
It is shown that spin-spin interactions rather than spin-lattice coupling control the dynamics of the magnetization formation visible in time-resolved luminescence and SQUID magnetometry of bulk and layered diluted magnetic semiconductors. A numerical solution of a nonlinear Schrödinger equation is applied to find the relation between formation time of the exciton magnetic polaron and relaxation time of the spin subsystem.Keywords
