DYNAMICAL CRITICAL BEHAVIOUR OF HEISENBERG FERROMAGNETS FOR T ≥ Tc
H. IroInstitut für theoretische Physik, Universität Linz, A-4040 Linz, Austria
Abstract
From an O(ε)-calculation (ε = 6 - d) of the dynamical spin correlation function in a Heisenberg system for T ≥ Tc an expression for that function applicable in dimension d = 3 is deduced. It comprises the expected limiting behaviour in different sectors of the critical region.
