Abstract
Starting with a general Hamiltonian of a one-dimensional antiferromagnet, H=J Sigma iSi.Si+1+A Sigma i(Siz)2-g mu BH Sigma Six D mod , mod A mod , H, and the effects on magnetisation are discussed. The results are compared with the phenomenological domain wall theory and agreement is found.Keywords
