Abstract
Resonance absorption in Fe3BO6 has been investigated for the low-frequency AFMR branch as a function of magnetic RF-field component direction in the bc crystal plane. Anisotropic character of absorption is shown to be due to complex character of weak ferromagnetic moment precession in orthorhombic crystals. Relation between the true resonance line width, and that observed in the quasi-optical experiment is discussed.
