High-frequency permeability of thin amorphous wires under an external field

We investigate the permeability of thin amorphous glass-covered Co-based wires up to GHz frequencies. The measured permeability μ ∥ parallel to the direction of the wires can be estimated by the Landau–Lifschitz equation. When an external field is applied, the resonance frequency varies which may be...

Description
Summary:We investigate the permeability of thin amorphous glass-covered Co-based wires up to GHz frequencies. The measured permeability μ ∥ parallel to the direction of the wires can be estimated by the Landau–Lifschitz equation. When an external field is applied, the resonance frequency varies which may be the result of the inhomogeneity of the anisotropy field inside the microwire.
