Description
A new procedure for calculation of the size of a critical region under the second order phase transition (PT) is proposed, and the formula for the quaintly τ* (τ* = (T* - Tc) / Tc defining this size is obtained, where T* is the temperature and Tc is the PT temperature. For τ < τ*, thermodynamic function of the system reveal a particular behaviour which can be described by using critical indices. It is shown that τ* depends on the ratio of the lattice constant to the radius of action of the interparticle potential b and decreases as b increases
