The Magnetostriction of Single Crystals of Iron-Silicon Alloys

Abstract

The spontaneous magnetostriction of iron-silicon alloys can be adequately described by two constants $h_1$ and $h_2$. For ordered alloys $h_1$ goes through zero at about 11 atomic percent silicon, $h_2$ at about 9 atomic percent silicon. In disordered alloys, in the composition range around 10 percent silicon, $h_1$ is somewhat larger than for the ordered alloys.
