However, neglecting fluctuations is grossly incorrect in the critical region, which is often not small (e.g., for typical ferromagnets it amounts to the upper ∼ 20% of the region below T c . in contrast, for conventional 3d- superconductivity the critical region is negligible).. Generally the neglected terms have a drastic influence on the critical exponents. In the critical region...

(Of course we choose the smallest possible integral values for the | ν i. The concentration ratios c i then result from (54.3) and (54.4) according to the principle that the entropy should not change in course of the equilibrium reaction. (54.5) where from the ideal gas equation (see the preceding subsection) for the yield function f (T , p)...

428 55 Conclusion to Part IV. 2 to the Hamilton function H ( p. although the meaning is completely different.. a) by differentiating the Helmholtz free energy with respect to T : S(T , V, N. b) from the difference expression S = 1. Here one should firstly keep in mind how these relations follow from a differ- ential formulation...
