Re-entrant ferromagnetism in a generic class of diluted magnetic semiconductors
M. J. Calderon, S. Das Sarma
Considering a general situation where a semiconductor is doped by magnetic impurities leading to a carrier-induced ferromagnetic exchange coupling between the impurity moments, we…
Mean field theory for double-perovskites
L. Brey, M. J. Calderon, S. Das Sarma +1
A mean field approximation of a model for double perovskites that takes into account the coupling between itinerant electron spins and localized spins is developed. As in previousl…
Theory of carrier mediated ferromagnetism in dilute magnetic oxides
M. J. Calderon, S. Das Sarma
We analyze the origin of ferromagnetism as a result of carrier mediation in diluted magnetic oxide semiconductors in the light of the experimental evidence reported in the literatu…
Impurity-Semiconductor Band Hybridization Effects on the Critical Temperature of Diluted Magnetic Semiconductors
M. J. Calderón, G. Gómez-Santos, L. Brey
We have studied the critical temperature of Diluted Magnetic Semiconductors by means of Monte Carlo simulations and Coherent-Potential-Approximation (CPA) calculations. In our mode…
