摘要：

Magnetic gap solitons which can be excited in the one-dimensional Heisenberg antiferromagnetic chain are considered. It is predicted that they may exist not only in the form of an envelope soliton but also in the form of a bound state of different kind vibrations of spins with odd and even sites, e.g. an envelope soliton and a kink.
