Ferromagnetism of magnetic semiconductors—Zhang-Rice limit
It is suggested that p-d hybridization contributes significantly to the hole binding energy Eb of Mn acceptors in III-V compounds, leading in an extreme case to the formation of Zhang-Rice-like small magnetic polarons. The model explains both strong increase of Eb and evolution of Mn spinresonance spectrum with the magnitude of valence-band offsets. For such a structure of Mn impurity in III-V ...
متن کاملTheory of Ferromagnetism in Diluted Magnetic Semiconductors
Carrier-induced ferromagnetism has been observed in several (III,Mn)V semiconductors. We review the theoretical picture of these ferromagnetic semiconductors that emerges from a model with kinetic-exchange coupling between localized Mn spins and valence-band carriers. We discuss the applicability of this model, the validity of a mean-field approximation for its interaction term widely used in t...
متن کاملCoherently photoinduced ferromagnetism in diluted magnetic semiconductors.
Ferromagnetism is predicted in undoped diluted magnetic semiconductors illuminated by intense sub-band-gap laser radiation. The mechanism for photoinduced ferromagnetism is coherence between conduction and valence bands induced by the light which leads to an optical exchange interaction. The ferromagnetic critical temperature T(C) depends both on the properties of the material and on the freque...

متن کاملZener model description of ferromagnetism in zinc-blende magnetic semiconductors
Ferromagnetism in manganese compound semiconductors not only opens prospects for tailoring magnetic and spin-related phenomena in semiconductors with a precision specific to III-V compounds but also addresses a question about the origin of the magnetic interactions that lead to a Curie temperature (T(C)) as high as 110 K for a manganese concentration of just 5%. Zener's model of ferromagnetism,...
