摘要
The phenomenological model of the magnetic phase transition in the nanocluster systems was considered within the framework of Landau expansion. We assumed that the thermodynamic potential includes entropic and field components, exchange interaction, distortion and pressure effects. The stationary value of relative magnetization and its temperature dependence were found. The effect of an external field on the phase transition and the temperature dependence of the susceptibility of the transition were investigated.
