摘要: We apply the resonant indirect exchange interaction theory to explain ferromagnetic properties of hybrid heterostructure consisting a InGaAs-based quantum well (QW) sandwiched between GaAs barriers with spatially separated Mn δ-layer. The experimentally obtained dependence Curie temperature on QW depth exhibits peak related region exchange. suggest theoretical explanation and fit this as result two contributions ferromagnetism—the intralayer contribution provided by QW.
