摘要：
Relaxation of thermoremanent magnetization (TRM) Of Cd1-xMnxTe diluted magnetic semiconductors (DMS) in the spin-glass state have been studied under light illumination. The relaxation of TRM can be described well by a power law decay, M(t)=M(t0)t(-alpha) (t>t0, t0 almost-equal-to 2 s). The variations of the decay parameter alpha with the illumination light intensity has been measured and a relation which indicates that alpha is proportional to the photogenerated carrier concentration n has been observed.
