Effect of hybridization on the magnetic properties of correlated two-band metals

The magnetic properties of transitionlike metals are discussed within the single-site approximation, which is a picture to take into account electron correlations. The metal is described by two hybridized bands one of which includes Coulomb correlation. The presented results indicate that ferromagne...

Zusammenfassung:The magnetic properties of transitionlike metals are discussed within the single-site approximation, which is a picture to take into account electron correlations. The metal is described by two hybridized bands one of which includes Coulomb correlation. The presented results indicate that ferromagnetism arises for adequate values of hybridization ( V ) , correlation ( U ) , and occupation number ( n σ ) . Some similarities with dynamical mean-field theory are indicated.
