Abstract
The spectrum of the longitudinal magnetisation in an isotropic model ferromagnet is calculated in 6- epsilon dimensions. The interaction with spin waves makes the transport coefficient diverge for small wavenumbers like k(d-6)3/. The regular part of the transport coefficient is also determined at k=0. A self-consistent extension of the approximation to arbitrary dimensions is briefly discussed.Keywords
