Abstract

For Fe-Ga single crystals, faster cooling rates achieved by metallic quench and ice-water quench extended the tetragonal magnetostriction constant, (3/2) lambda(100), to higher Ga contents than reported previously. The maximum magnetostriction measured was 420 ppm at a composition of 21.4 at.% Ga. Using these faster cooling rates, the formation of short-range order (SRO) was obviously suppressed in A2 single phase, while this change in SRO did not significantly affect (3/2) (lambda 100).
