Correlations in the thermodynamical theory of phase transitions of the second kind. II

In the frameworks of the geometrical approach developed earlier, the situation is considered when in the branch point of the zero-field curve the first non-vanishing derivatives of the Gibbs potential w.r.t. the order parameter and w.r.t. the “critical” correlation parameter are of the sixth order. The critical exponents obtained are . The results show that using the proposed approach it is possible to forge a purely thermodynamical realistic theory of second-order phase transitions.
