RENORMALIZED FIELD THEORY FOR THE STATIC CROSSOVER IN DIPOLAR FERROMAGNETS
E. Frey et F. SchwablInstitut für Theoretische Physik, Physik-Department der Technischen Universität München, D-8046 Garching, F.R.G.
Abstract
A field theoretical description for the static crossover in dipolar ferromagnets is presented. New non leading critical exponents for the longitudinal static susceptibility are identified and the existence and magnitude of the dip in the effective critical exponent of the transverse susceptibility found by matching techniques is scrutinized.
