Charge Density Wave Driven Ferromagnetism in the Periodic Anderson Model
M. A. Majidi, D. G. S. P. Doluweera, B. Moritz +3
We demonstrate the existence of ferromagnetism in the Periodic Anderson Model (PAM) at conduction-band filling near a quarter. We show that this ferromagnetism is not supported by…
Dynamics of Impurity and Valence Bands in GaMnAs within the Dynamical Mean Field Approximation
M. A. Majidi, J. Moreno, M. Jarrell +2
We calculate the density-of-states and the spectral function of GaMnAs within the dynamical mean-field approximation. Our model includes the competing effects of the strong spin-or…
Short-Range Ordered Phase of the Double-Exchange Model in Infinite Dimensions
R. S. Fishman, F. Popescu, G. Alvarez +2
Using dynamical mean-field theory, we have evaluated the magnetic instabilities and T=0 phase diagram of the double-exchange model on a Bethe lattice in infinite dimensions. In add…
Transition Temperature of a Magnetic Semiconductor with Angular Momentum j
Juana Moreno, Randy S. Fishman, Mark Jarrell
We employ dynamical mean-field theory to identify the materials properties that optimize Tc for a generalized double-exchange (DE) model. We reach the surprising conclusion that Tc…
Thermodynamic Consistency of the Dynamical Mean-Field Theory of the Double-Exchange Model
Randy S. Fishman, Juana Moreno, Thomas Maier +1
Although diagrammatic perturbation theory fails for the dynamical-mean field theory of the double-exchange model, the theory is nevertheless Phi-derivable and hence thermodynamical…
Magnetism in semiconductors: A dynamical mean field study of ferromagnetism in Ga_{1-x}Mn_xAs
K. Aryanpour, J. Moreno, M. Jarrell +1
We employ the dynamical mean field approximation to perform a systematic study of magnetism in Ga_{1-x}Mn_xAs. Our model incorporates the effects of the strong spin-orbit coupling…
