Abstract
Using numerical transfer‐integral and molecular‐dynamic calculations, we demonstrate that the mapping of an easy‐plane ferromagnet in a field to the sine‐Gordon system fails at surprisingly low temperatures. The crucial implication for CsNiF3 is that the central peak observed by Kjems and Steiner at T = 10 K is more likely to be due to multimagnon difference processes, or pulse‐soliton features of the nearly isotropic model rather than due to kink or breather solitons.This publication has 15 references indexed in Scilit:
