Abstract

The dependence of the absorption spectra of CsCoCl3 on temperature and a magnetic field was investigated. It was found that the energy difference between the exciton line and its hot sideband is nearly equal to the soliton energy, and the intensity of the hot band is proportional to the thermal probability of the soliton below TN1. Therefore, it was concluded that the hot band is ascribed to the exciton creation at the thermally excited soliton.
