Abstract

Summary form only given. Certain substitutional additions to Fe can increase both its resistivity and magnetostriction /spl lambda/. Recently Fe-Ga has been investigated as a bulk magnetostrictive material, with maximum /spl lambda/ localized along the <100>. Further, it has been discovered that /spl lambda/ along <100> increased from /spl sim/300 to /spl sim/350 ppm when the samples were quenched, rather than furnace-cooled. Fe-Ga, due to its low anisotropy and high magnetostriction is an attractive candidate as a high magnetostrictive susceptibility MEMS material. In order to investigate the thin film properties of Fe-Ga materials epitaxial fabrication is necessary, in order to locate the <100> in specific orientations.
