摘要：

The group-theoretic technique described in an earlier paper is used to calculate the free spin wave energies for both magnetic phases of haematite. It is shown that the optic modes may have unusually low energy in α-Fe 2O3, and that molecular field theory gives correct results for magnetic resonance.
