摘要：

Mossbauer spectroscopy has been performed on hematite (alpha-Fe2O3) which had been irradiated by the continuous spectrum of reactor neutrons. The normal Morin transition was observed but at a lower temperature a new reverse Morin transition occurred. This new transition can be explained on the basis of the radiation damage reducing the magnetic single-ion anisotropy energy.
