摘要：
The main conclusions of a theoretical investigation of magnon-interaction effects in α-Fe2O3 are briefly reported. It is shown that the optic modes can have very low energy and it is suggested that these modes may play an important role in the mechanism of the Morin phase transition. © 1969 The American Physical Society.
