Multi-Orbital Lattice Model for (Ga,Mn)As and Other Lightly Magnetically Doped Zinc-Blende-Type Semiconductors
A. Moreo, Y. Yildirim, G. Alvarez
We present a Hamiltonian in real space which is well suited to study numerically the behavior of holes introduced in III-V semiconductors by Mn doping when the III ion is re…
Magnetic Instabilities and Phase Diagram of the Double-Exchange Model in Infinite Dimensions
R. S. Fishman, F. Popescu, G. Alvarez +3
Dynamical mean-field theory is used to study the magnetic instabilities and phase diagram of the double-exchange (DE) model with Hund's coupling J_H >0 in infinite dimensions. In a…
Critical Temperatures of a Two-Band Model for Diluted Magnetic Semiconductors
F. Popescu, Y. Yildirim, G. Alvarez +2
Using Dynamical Mean Field Theory (DMFT) and Monte Carlo (MC) simulations, we study the ferromagnetic transition temperature Tc of a two-band model for Diluted Magnetic Semiconduct…
Study of the One- and Two-Band Models for Colossal Magnetoresistive Manganites Using the Truncated Polynomial Expansion Method
C. Sen, G. Alvarez, Y. Motome +5
Considerable progress has been recently made in the theoretical understanding of the colossal magnetoresistance (CMR) effect in manganites. The analysis of simple models with two c…
