Abstract
Light-induced change in the optical absorption of the garnet Ca3Mn2Ge3 O12 has been found. The magnitude of the light-induced optical absorpt ion does not depend on the polarization state of the exciting illumina tion. The effect persists for a long time at low temperatures and can be attributed to light-induced generation or redistribution of Mn4+ io ns in the crystal. (C) 1998 American Institute of Physics.
