Effect of hybridization on the magnetic properties of correlated two-band metals
C. M. Chaves, A. Troper
The magnetic properties of transition-like metals are discussed within the single site approximation, which is a picture to take into account electron correlations. The metal is de…
Model for spin coupling disorder effects on the susceptibility of antiferromagnetic nanochains
C. M. Chaves, Thereza Paiva, J. d'Albuquerque e Castro +1
The temperature dependence of the static magnetic susceptibility of exchange-disordered antiferromagnetic Heisenberg spin-1/2 finite chains with an odd number of spins is investiga…
Ferromagnetism in two band metals: Combined effect of Coulomb correlation, hybridization and band widths
C. M. Chaves, A. Troper
We study the possibility of ferromagnetism in metals. The metal is described by two hybridized bands one of which includes Hubbard correlation whereas the other is uncorrelated. We…
Cross effect of Coulomb correlation and hybridization in the occurrence of ferromagnetism in two shifted band transition metals
C. M. Chaves, A. Troper
In this work we discuss the occurrence of ferromagnetism in transition-like metals. The metal is represented by two hybridized() and shifted ) bands one of which includes…
On the use of a single site approximation to describe correlation in pure metals
C. M. Chaves, A. A. Gomes, A. Troper
The magnetic properties of pure transition-like metals are discussed within the single site approximation, to take into account the electron correlation. The metal is described by…
