We carefully investigated the ferromagnetic coupling in the as-grown and annealed ferromagnetic semiconductor GaMnAs/A1GaMnAs bilayer devices. We observed that the magnetic interaction between the two layers strongly ...
Hydrogenic acceptor binding energy as a function of dot radius in a GaMnAs/Ga_(0.6)Al_(0.4)As quantum dot is calculated including the exchange interaction of Mn alloy content with an itinerant carrier.Calculations...
