The magnetostriction and the magnetic properties of amorphous Sm[sub x]Fe[sub 100[minus]x] thin films prepared by sputtering were investigated at room temperature. The magnetostriction, -[lambda], of these films increased rapidly in low fields (<1kOe) and reached the maximum values of 300--400[times]10[sup [minus]6] at 16kOe for x = 30--40. These results suggest that Sm-Fe thin films could be used for micro-actuators. lie magnetic properties of Sm-Fe thin films did not show clear dependence on the sputtering conditions such as input power, Ar gas pressure, and substrate temperature.
