An interacting-spin-wave theory is presented for describing the behavior of a classical Heisenberg ferromagnetic chain in an external magnetic field. All static and dynamical longitudinal properties can be analitically calculated by means of a nonperturbayive Green's-function approach.

Abstract
An interacting-spin-wave theory is presented for describing the behavior of a classical Heisenberg ferromagnetic chain in an external magnetic field. All static and dynamical longitudinal properties can be analitically calculated by means of a nonperturbayive Green's-function approach.
