Abstract :
The aim of this paper is to investigate FeCuSiBNb nanocrystalline microwires as an alternative to amorphous Co-based high-permeability microwires. The anisotropy is determined through static characterization from 20degC to 250degC using a VSM (Vibrating Sample Magnetometer). The properties are comparable in term of softness, but are superior in terms of saturation magnetostriction and thermal stability. These materials are therefore attractive for high-frequency Giant Magnetoimpedance applications.
