Abstracts

EN

The spin-lattice relaxation in CdMnTe at 4.7 K has been measured at high magnetic fields up to 24.5 T. At fields, where the ground state of nearest-neighbor exchange coupled Mn pairs changes due to energy level crossing, an increase in the relaxation rate is observed. This is attributed to the change of relaxation of nearest-neighbor Mn pairs. It proves that not only large size Mn clusters are involved in the relaxation as it has been shown previously, but also Mn pairs. It shows as well that the mixing of pair states is quite effective.
