We report on the formation of self-assembled semimagnetic (Cd, Mn)Se quantum dots via thermally activated reorganization of an initially two-dimensional film. Incorporation of Mn causes a marked decrease of the dot density, while the size is only slightly affected. Magneto-optical data are consistent with a homogeneous distribution of the magnetic ions. We observe g factors as large as 200, enabling control of individual carrier spins on a sub 10 nm length scale. © 2001 American Institute of Physics.
