Low-field microwave magnetic permeability on FeSiBNbCu thin films

摘要

This work presents the dynamic and static magnetic properties of an 85 nm-thick amorphous thin film precursor of the well-known Finemet material, deposited by RF sputtering. Hysteresis evidences in-plane isotropic properties that are distinguished as contributions of hard and soft axis simultaneously. High-frequency permeability measurements were performed by using the network inductive method in the frequency range 100 kHz-1.8 GHz. The low-field FMR relation dispersion obtained from the permeability spectra shows peculiar properties. from which the effects of stress-induced anisotropy are discussed. (c) 2006 Elsevier B.V.
