Abstract
Using general thermodynamic identities and inequalities, the critical behavior of integrals involving dynamic spin-correlation functions are discussed. For intrinsic spin interactions and a large class of integrands, including most cases of physical interest, it is shown that the most singular terms are of two types, the instantaneous-approximation result and a term directly proportional to the energy. It is shown that this holds for the dynamic correlation function itself. The critical behavior of the resistivity, thermopower, and thermal conductivity in magnetic metals are discussed explicitly.
