The Raman optical activity (ROA) of magnons in rutile-structure antiferromagnetic FeF₂ (TN = 78 K) has been studied as a function of temperature and applied magnetic field. For exciting light incident along the c axis, ROA is observed for magnons but not for phonons. In zero field, a small splitt...
