文摘

The magnetic polaritons in free plates of a weak ferromagnet FeBO₃ are excited at 77 K with frequencies of 30–75 GHz. Polariton modes on both sides of the line of uniform antiferromagnetic resonance are observed in a thick plate which is magnetized in the basal plane. The experimental method is described. The nature of resonances for volume and surface polariton modes in iron borate is considered.
