Structural and magnetic properties of ferromagnetic In1−xMnxAs1−yPy layers

Electronic structure of substitutional Mn in epitaxial In0.965Mn0.035Sb film

“…[2][3][4] For example, recent reports on InMnAs alloy grown by metalorganic vapor phase epitaxy ͑MOVPE͒ have shown the presence of spin polarized itinerant carriers at room temperature. 5,6 While the detailed origin of the exchange interaction in this alloy system is controversial, the source of the localized spins has been attributed to atomic scale complexes consisting of electronically active dimers ͑Mn 2 ͒ and trimers ͑Mn 3 ͒ that stabilize the ferromagnetism. 7 The Mn complexes presumably participate in p-d exchange coupling that persists up to temperatures above room temperature ͑RT͒, with itinerant holes and lead to an enhanced T C .…”
