We demonstrate the introduction of high carrier densities into two and three-dimensional magnetic semiconductor heterostructures that contain large local concentrations of magnetic moments. The use of (ZnSe)m-f(MnSe)f digital alloys readily allows the fabrication of epilayer samples of moderate Mn composition with carrier concentrations up to ∼ 1019 cm-3. Modulation doping of ZnSe/Zn1-x-yCdyMnxSe quantum wells enables the fabrication of a 2-D electron gas confined within the magnetic region with sheet concentrations up to ∼6X1011 cm-2.
