The spin-lattice relaxation (SLR) time of Cd_{1-x}Mn_{x}Te with x=0.008 is measured directly under electron spin resonance condition in a magnetic field of 8.9 T, using a pick-up coil. The SLR times are measured for different sample temperatures between 3.0K and 35K and compared with data of a more diluted sample with x=0.002. The SLR times are shorter than expected for single spin SLR. Moreover, the temperature dependence of the SLR time does not show any of the characteristic behaviours for single spin SLR. Thus, the observed SLR times are explained by cross relaxation of single spins with spin clusters.
