Ferromagnetic Resonance in a Uniaxial Anisotropic Ferrite: BaFe12O19

摘要

Ferromagnetic resonance has been observed in a single‐crystal sample of barium ferrite, BaFe12O19, under both single‐domain and multidomain conditions, for orientations of the static field from 0°–90° with the easy axis of magnetization. The results verify in detail the predictions of the theory of Smit and Beljers for single‐domain conditions, and show qualitative agreement with the multidomain theory.
