• A study is made of solitons in the classical Heisenberg ferromagnetic chainwith easy-plane anisotropy in the presence of an out-of-plane magnetic field.Two types of solitons are found, i.e., solitons have no internal degree of freedomin low fields while they have it in high fields. The excitation spectrum is obtainedand discussed from the standpoint of solitons. In zero field the antiferromagnet-like magnon excitation is due to be a kink being degenerate with an antikink.
