Non-linear effects in the easy-plane one-dimensional antiferromagnet in a staggered field.
(1991) Cassino, Flávio Sandro Lays; Pires, Antônio Sergio Teixeira
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.
