In diluted magnetic semiconductors (DMSs), extended sp-carriers strongly couple with localized d-electrons of transition metal ions. This sp-d exchange interaction causes interesting magneto-optical phenomena of DMSs. Large Faraday effect of Cd_1-xMn_xTe can be used for an integration of magneto-optical waveguide with semiconductor optical devices. The sp-d exchange interaction can be used for the manipulation of the motion of Mn²⁺ in Cd_1-xMn_xTe by ultrafast laser pulses. We also discuss magneto-optical properties of new DMSs.
