GOLDSTONE SINGULARITIES IN ISOTROPIC FERROMAGNETS

Abstract
The equation of state and the susceptibilities of isotropic magnets are calculated in exponentiated scaling form to O(ε) by repetitive use of the trajectory integral method. The resulting coexistence-curve singularities do not depend on the dimension for d ≥ 3 since the Goldstone modes show Fisher-renormalized classical tricritical behaviour.
