研究了成分对直流磁控溅射制备的Fe-Sm合金薄膜磁致伸缩性能的影响。所形成的膜的组成为24~59at%Sm。Fe-Sm薄膜的磁致伸缩为负，即压缩磁致伸缩。薄膜的磁致伸缩随Fe-Sm合金的成分比例不同而变化。对于Fe-Sm非晶薄膜，在1200kA/m下观察到24-34at%Sm的超磁致伸缩(GM)，在1200kA/m时超过1000ppm。在1200kA/m时，Fe-29.3at%Sm合金膜的Gm极限值为1280ppm。
Influences of composition on magenetostriction of Fe–Sm alloy thin films prepared by D.C. magnetron sputtering process were investigated. Composition of formed film was ranged from 24 to 59 at%Sm. Negative, that is, compressive magnetostriction was observed of Fe– Sm thin films. The magenetostriction of thin films was varied with composition rate of Fe–Sm alloy. The giant magnetostriction (GM) over 1000 ppm at 1200 kA/m was observed from 24 to 34 at%Sm for Fe–Sm amorphous film. The limited value of GM at 1200 kA/m was 1280 ppm of Fe–29.3 at%Sm alloy film.
