Abstract
We apply the semiclassical approach to calculate the combined effect of quantum corrections and out-of-plane fluctuations on the soliton contribution to the specific heat in the one-dimensional easy-plane ferromagnet. We show that the importance of quantum corrections is greatly enhanced by going beyond the sine-Gordon approximation. We argue that the remaining discrepancy in experiments in CsNiF3 and chab arises from the approximations required in the semiclassical approach. The quantitative interpretations of neutron scattering and specific heat data on CsNiF3 are shown to be closely parallel.
