Abstract

Spherical, granular and flake-type powders are used to fabricate polymer-bonded composites of an Fe-Co based alloy and their magnetostrictive properties are compared. Magnetostrictive sensitivity at low applied fields is best for the composites fabricated with flake-type powders. Also, in the case of flake-type powders, a high magnetostriction of 200 ppm is obtained at an applied field of 4.3 kOe under a suitable compressive pre-stress.
