Resumo
We present a theoretical analysis of soliton excitations in an easy-plane classical one-dimensional antiferromagnet in the presence of a staggered magnetic field transverse to the chain direction. The out-of-plane soliton solution is found to have an instability similar to the one found before by Magyari-Thomas-Kumar for the easy-plane ferromagnetic chain in an external magnetic field.
