Disorder effects in diluted magnetic semiconductors
In recent years, disorder has been shown to be crucial for the understanding of diluted magnetic semiconductors. Effects of disorder in these materials are reviewed with the emphasis on theoretical works. The types and spatial distribution of defects are discussed. The effect of disorder on the intimately related transport and magnetic properties are considered from the viewpoint of both the ba...
متن کاملEffects of disorder on ferromagnetism in diluted magnetic semiconductors.
We present results of a numerical mean-field treatment of interacting spins and carriers in doped diluted magnetic semiconductors, which takes into account the positional disorder present in these alloy systems. Within our mean-field approximation, disorder enhances the ferromagnetic transition temperature for metallic densities not too far from the metal-insulator transition. Concurrently, the...
متن کاملANALYSIS 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...

electron energy relative to the valence band top for x 0:05, averaged over 100 configurations of 200 Mn impurities (dark gray area). The light gray bar denotes the GaAs gap. The dashed line shows the Fermi energy for p 0:1. Inset: Average Mn (positive) and hole (negative) spin polarizations for the same parameters. The dotted curves have been obtained with overlap matrix elements t r > 0 as in ...
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...
