Acesso em: 05 dez. 2012.00381098http://www.repositorio.ufop.br/handle/123456789/2005We 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.en-USNon-linearAntiferromagnetMagnetic fieldArtigo publicado em periodicoO periódico Solid State Communications concede permissão para depósito do artigo no Repositório Institucional da UFOP.
