  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.
