Photoinduced changes of the field of the phase transition from the antiferromagnetic to the metamagnetic state have been found in the garnet. This effect is interpreted as related to the experimentally detected photoinduced magnetic moment. The observed photoinduced effect persists during a long time at low temperatures.
