Abstract
The phase transition is investigated for ordered and structurally disordered Heisenberg ferro- and ferrimagnets. No influence of disorder on the critical exponents is found, but a characteristic non-monotonic temperature dependence of the Kouvel-Fisher exponent γ(T) outside the critical regime, which is described by the correlated molecular field theory.
