Preparation and Magnetostriction of Epoxy-Bonded Pr(Fe_0.4Co_0.6)_1.93 Composites

Abstract

The magnetostrictive Pr(Fe0.4Co0.6)1.93alloy with MgCu2-type structure, and its 0-3 and pseudo 1-3 type epoxy-bonded composites were fabricated by curing without and with a magnetic field. The structural, magnetic and magnetoelastic properties were investigated by means of x-ray diffraction, a vibrating sample magnetometer and a standard strain technique. The 0-3 type composite has a larger magnetostriction than the 1-3 composite has, which can be ascribed to the easy magnetization direction (EMD) not lying along direction.
