“…For example, the effect of three-dimensional confinements on the magnetic polaron and magnetic fluctuation in nanoscale were studied by magneto-optical spectroscopy based on DMS QD systems [4][5][6]. Furthermore, the anti-parallel spin interaction between carriers localized in the zero-dimensional structure was identified in coupled QD systems consists of DMS and non-DMS materials [7,8]. In spite of such a great deal of attention given to understand new physical properties arising from incorporation of magnetic ions in the QD systems, the detail growth process for QD formation and the evolution of dots in DMS QD systems have not been systematically studied.…”
