Abstract: The influence of lattice strain on the magnetic properties of Mott-Hubbard material has been analyzed within the Green function formalism with application of quasiparticle energy spectra in the strong Coulomb repulsion limit. The obtained results reproduce qualitatively correct dependence of T_C on the external pressure and quantitatively agree with the experimental data.
