Abstract
The aging behaviour of spin glass semiconductor Cd1-xMnxTe subjected to bond perturbation was studied by means of the direct change in the spin–spin interaction ΔJ using photo illumination, without change in temperature. Under the ΔJ perturbation, the maximum of relaxation rate of magnetization S at the time tmax is suppressed and tmax becomes longer with increasing the light intensity. The former is consistent with the droplet picture, but the latter indicates that the ΔJ perturbation accelerates the magnetic relaxation so as to contradict with the chaotic nature of spin configuration under the perturbation.
