The Collinear Magnetic Phases of the Geometrically-Frustrated Antiferromagnet CuFeO: The Importance of Stacking
R. S. Fishman, F. Ye, J. A. Fernandez-Baca +2
The correct stacking of hexagonal layers is used to obtain accurate estimates for the exchange and anisotropy parameters of the geometrically-frustrated antiferromagnet CuFeO.…
Magnetic Interaction in the Geometrically Frustrated Triangular Lattice Antiferromagnet
F. Ye, J. A. Fernandez-Baca, R. S. Fishman +4
The spin wave excitations of the geometrically frustrated triangular lattice antiferromagnet (TLA) have been measured using high resolution inelastic neutron scatteri…
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…
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…
Slater Transition in the Pyrochlore Cd2Os2O7
D. Mandrus, J. R. Thompson, R. Gaal +7
Cd2Os2O7 crystallizes in the pyrochlore structure and undergoes a metal-insulator transition (MIT) near 226 K. We have characterized the MIT in Cd2Os2O7 using X-ray diffraction, re…
