Abstract

A method of preparing a magnetostrictive material, including the steps of:
(a) forming a melt of metals having a composition corresponding to the magnetostrictive material;
(b) subjecting the melt to a micro-gravity environment; and (c) cooling the melt in the micro-gravity environment at a rate of at least 50°C per second, while applying a magnetic field to the melt, to solidify the melt.
