Abstract
We study the influence of the addition of the Co ions on the spin-lattice relaxation rate in the (Cd,Mn)Te system. The magnetization relaxation is measured by time-resolved spectroscopy of single (Cd,Mn,Co)Te/(Cd,Mg)Te quantum wells in a magnetic field. We find that even a relatively small cobalt admixture significantly shortens the Mn relaxation time.
