Theoretical models of ferromagnetic III – V semiconductors q
Recent materials research has advanced the maximum ferromagnetic transition temperature in semiconductors containing magnetic elements toward room temperature. Reaching this goal would make information technology applications of these materials likely. In this article we briefly review the status of work over the past five years which has attempted to achieve a theoretical understanding of thes...
متن کاملFerromagnetic semiconductors
The current status and prospects of research on ferromagnetism in semiconductors are reviewed. The question of the origin of ferromagnetism in europium chalcogenides, chromium spinels and, particularly, in diluted magnetic semiconductors is addressed. The nature of electronic states derived from 3d of magnetic impurities is discussed in some detail. Results of a quantitative comparison between ...
متن کاملWhy ferromagnetic semiconductors ?
Rapid development of information technologies originates from the exponential increase in the density of information that can be processed, stored, and transfer by the unit area of relevant devices. There is, however, a growing amount of evidences that the progress achieved in this way approaches its limits. Various novel ideas put forward to circumvent barriers ahead are described. Particular ...
متن کاملElectronic Quasiparticle Spectrum of Ferromagnetic Semiconductors
We discuss the electronic quasiparticle spectrum of a ferromagnetic semiconductor, within the framework of the s-f model. Some exactly calculable limi ting cases (ferromagnetic saturation, atomic limit, centre of gravity of the conduction band, ....) as well as approximate theories for the general case are reviewed in order to understand the influence of temperature and finite band filling on t...
متن کاملTheory of ferromagnetic (III,Mn)V semiconductors
The body of research on (III,Mn)V diluted magnetic semiconductors initiated during the 1990’s has concentrated on three major fronts: i) the microscopic origins and fundamental physics of the ferromagnetism that occurs in these systems, ii) the materials science of growth and defects and iii) the development of spintronic devices with new functionalities. This article reviews the current status...
