Title: Magnetostriction in a Co-30%Fe alloy

Abstract

The authors have studied the magnetostriction and magnetic properties of a deformed and annealed Co-30%Fe alloy. The cold-rolled and annealed (at 820 C for 40 min) sample exhibits a substantial magnetostriction of {approximately}110 x 10{sup {minus}6} at a practical, low field of {approximately}100 Oe, while only {approximately}10 x 10{sup {minus}6} for the same applied field is obtained for the as-cold-rolled sample. The saturation magnetostriction of the annealed Co-30%Fe alloy was {approximately}140 x 10{sup {minus}6}, which is significantly affected by the cold-rolling and annealing processes. This drastic dependence of the magnetostriction behavior on the alloy processing is believed to be a result of the microstructure and residual stress changes brought about by the heat treatment processing.
