A sign reversal of the magnetic hysteresis has been observed in CeTe/CdMnTe superlattices when the sample is excited by unpolarized light in the region of interband transitions. This effect stems from a nonequilibrium magnetization of manganese ions during spin relaxation of photogenerated carriers at Zeeman sublevels in the magnetic field. © 1995 American Institute of Physics.
