Abstract

The m-magnon bound state (or soliton) excitation spectrum of an exactly solvable generalisation of the Heisenberg spin chain with arbitrary S is described. It is in qualitative agreement with predictions based on the classical continuum model. The classical limit of the generalised model is obtained.
