26 Apr 2001 | | Subject: | Strongly Correlated Electrons | cond-mat.str-el | | Affiliation: | Ternopil State Technical University, Ukraine | | Abstract: | In the paper a possibility of metallic ferromagnetic state realization in a generalized Hubbard model with more complete accounting of electron-electron interactions, in particular, the correlated hopping and exchange interaction integrals is investigated. Recently obtained by means of mean-field approximation single electron energy spectrum is used for the description of finite temperature properties of the system. In the paper the expression for the critical temperature of ferromagnet-paramagnet transition is found, the behaviour of temperature dependencies of magnetization and paramagnetic susceptibility is analyzed. Taking into account the correlated hopping allows to explain some peculiarity of ferromagnetic behaviour of transition metals, their alloys and compounds. | | Source: | arXiv, cond-mat/0104515 | | Services: | Forum | Review | PDF | Favorites | |
