Microstructure and mechanical properties

Dynamic properties of the weak ferromagnet FeBO 3 were investigated. The dependence of resonance absorption χ" on the angle between the easy plane of magnetizations and the RF field is shown. The calculation of the frequency dependence of the resonant precession modes for the low- and high-frequency branch is presented. Experimental results for the low-frequency branch show good agreement with theory.
