Анотація | The phenomenological model of the first-order phase transition between the paramagnetic and magneto-ordered states of the nanocluster system was presented in the paper. In addition to the main thermodynamic components, intercluster interaction and the effect of external pressure were included into the dependence of the free energy. The temperature dependence of the stationary value of relative magnetization and the critical value of pressure, at which a transition is possible, were found. |
