Abstract

High frequency magnetomechanical performance offered by 2-2 composites with internal magnetic biasing was reported. The multilayer structure was made up of layers of Terfenol-D and Nd₂Fe₁₄B which were bonded by cyanoacrylate adhesive. The saturation magnetostriction, magnetization, permanent internal magnetic field and permeability were measured. The coupling coefficient was also measured using the three parameter technique.
