Abstract
Magnetostriction and magnetic properties of bcc Fe-Co-Sm alloys produced by DC triode sputtering method were investigated. An addition of 3 at% Sm suppressed large positive magnetostriction of bcc Fe-Co alloys, resulting in almost zero magnetostriction in the vicinity of bcc Fe0.7C0.3 alloys. These nonmagnetostrictive alloys show a high saturation magnetization of about 210 emu/g, and thus are thought to be useful for soft magnetic materials.
