摘　　要：Under normal condition, crystal hematite undergoes phase transition from antiferromagnetism to weak ferromagnetism at 260 K and the spin orientation changes from crystal axis [1121] to (1121)plane which is called Morin transition. At high temperature (T】260 K ) crystal hematite displays weak ferromagnetism due to the existence of
