Abstract
We report on spin orientation and alignment of ions in (Cd,Mn)Te diluted magnetic semiconductor crystals using resonant intracenter excitation with circular- and linear-polarized light. The resulting polarized emission of the magnetic ions is observed at low temperatures when the spin relaxation time of the ions is in the order of , which considerably exceeds the photoluminescence decay time of . We demonstrate that the experimental data on optical orientation and alignment of ions can be explained using a phenomenological model that is based on the approximation of isolated centers.
