Ferromagnetic resonance, magnetic behaviour and structure of Fe-based glass-coated microwires

Natural ferromagnetic resonance (NFMR), hysteresis loops and X-ray diffraction have been studied in the Fe-rich microwires with a ratio ρ of the metallic nucleus diameter to the total diameter of the microwires ranging between 0.1 and 0.4. Both coercivity, H c, and frequency of the NFMR, ω res, incr...

Description
Summary:Natural ferromagnetic resonance (NFMR), hysteresis loops and X-ray diffraction have been studied in the Fe-rich microwires with a ratio ρ of the metallic nucleus diameter to the total diameter of the microwires ranging between 0.1 and 0.4. Both coercivity, H c, and frequency of the NFMR, ω res, increase as ρ decreases. The splitting of ω res was explained from the coexistence of crystalline and amorphous phases.
