In this work we discuss the occurrence of ferromagnetism in transition-likemetals. The metal is represented by two hybridized($V$) and shifted$(\epsilon_s$) bands one of which includes Hubbard correlation whereas theother is uncorrelated. The starting point is to transform the originalHamiltonian into an effective one. Only one site retains the full correlation(U) while in the others the correlations are represented by an effective field,the self-energy(single-site approximation). This field is self-consistentlydetermined by imposing the translational invariance of the problem. Thereby onegets an exchange split quasi-particle density of states and then anelectron-spin polarization for some values of the parameters $(U,V, \alpha,\epsilon_s)$, $\alpha$ being the ratio of the effective masses of the two bandsand of the occupation number $n$.

Cross effect of Coulomb correlation and hybridization in the occurrence of ferromagnetism in two shifted band transition metals
