Keywords:Fe-Ga, vertical Bridgman, magnetostriction
We have developed a manufacturing process of Fe-Ga magnetostrictive alloys which were available for materials of vibration power generators, from single crystal growth using a vertical Bridgman (VB) method to thin-plate processing. In order to stabilize the power generation output of the vibration power generators, it is necessary to produce Fe-Ga single crystal member so that magnetostriction by applying magnetic field parallel λ|| is maximized. We tried to improve the magnetostrictive characteristics by surface processing.
