In the framework of mean-field theory, the phase transition paramagnet–ferromagnet is investigated for the deformed partition function. The influence of the non-extensive parameter q on the free-energy density and the steady-state value of order parameter is studied in the Landau approximation.</p>}, number={5}, journal={Ukrainian Journal of Physics}, author={Yushchenko, O.
