Abstract
We study the influence of small amplitude fluctuations on the soliton induced dynamic structure factors of the classical one dimensional antiferromagnet with two single ion anisotropies. In contrast to the case of an external magnetic field the equations of motion for the in-plane and out-of-plane fluctuations separate and can be solved exactly.
