“…The substitution of nonmagnetic Ga in Fe enhances the magnetostriction k over tenfold, which has drawn lots of attentions [1][2][3][4]. With relatively high magnetostriction, low coercivity and good ductility, Fe-Ga alloy is a promising magnetostrictive material for magnetic actuators and sensors [5][6][7][8][9][10][11][12].…”
