[10p-N221-4] Magnetostrictive Control of Fe-Ga single crystals by surface processing

Kiyoshi Izumi1, Kazuhiko Ohkubo1, Shotaro Kawamura1, Masaaki Sato1 (1.Sumitomo Metal Mining)

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.
