ANALYSIS OF SOME MAGNETIC PROPERTIES OF DILUTED MAGNETIC SEMICONDUCTORS
The susceptibility and specific heat experimental results of the diluted magnetic semiconductors (DMS) are incorporated in a model based on short-range as well as long-range interaction in a random may of magnetic ions. The so-called nearestneighbor pair approximation (NNPA) is applied. It appears that the calculated values of zero field specific heat and Curie-Weiss temperature based on th...
متن کاملTransport and magnetic properties of the diluted magnetic semiconductors
We report on electrical transport and magnetic properties of quaternary single crystals of Sb 1.98–x V 0.02 Cr x Te 3 and Sb 1.984–y V 0.016 Mn y Te 3 with x ranging from 0 to 0.022 and y ranging from 0 to 0.034 over temperatures from 2 K to 300 K. Ternary crystals Sb 2–z V z Te 3 were reported to have rather small magnetization in the ferromagnetic state due to low spin of vanadium ions. There...
متن کاملPart II Diluted Magnetic Semiconductors First-Principles Study of the Magnetism of Diluted Magnetic Semiconductors
We report the density-functional-theory calculations of the exchange interactions and Curie temperature for a series of III-V and II-VI diluted magnetic semiconductors. We focus the discussion on the role of the holes in the establishing the ferromagnetic order in various systems. We suggest a method of the quantitative characterization of the properties of the holes. It is shown that there are...
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 کاملQuantum Transport in Diluted Magnetic Semiconductors
The chapter highlights selected electric charge transport phenomena studied recently in low dimensional structures of DMSs. The first part describes transport phenomena related to the quantum interference of scattered electron waves in diffusive transport regime at the boundary of metalinsulator transition. The second part is devoted to Landau quantization of electronic states, as quantum Hall ...
