Quasi-two-dimensional diluted magnetic semiconductors with arbitrary carrier degeneracy

Abstract

In the framework of the generalized mean-field theory, conditions for the ferromagnetic state in a two-dimensional diluted magnetic semiconductor and the features of that state are defined. The Ruderman-Kittel-Kasuya-Yosida interaction of magnetic impurities is supposed. The spatial disorder of their arrangement and temperature alteration of the carrier degeneracy are taken into account.
