On the Magnetostriction of Iron-Silicon-Cobalt Alloys

Abstract

The magnetostriction of ternary alloys of iron,silicon and cobalt have been measured in various longtudinal magnetic fields of less than 1100 Oersteds. The positive magnetostriction of Iron-Cobalt system gradually decreases with the addition of Silicon, and we obtain the saturation magnetostriction λ_s=0 line. This line crosses to the superlattice line,connecting with Fe₃Si and FeCo, through the maximum range of permeability.
