Lim, SH Choi, YS Han, SH Kim, HJ Shima, T Fujimori, H 2024-01-21T16:39:01Z 2024-01-21T16:39:01Z 2021-09-03 1998-10 0304-8853 https://pubs.kist.re.kr/handle/201004/142842 Magnetostriction of amorphous Sm-Fe and Sm-Fe-B thin films is systematically investigated over a wide composition range from 14.1 to 71.7 at% Sm. In the case of Sm-Fe-B thin films, the amount of B is varied from 0.3 to 0.8 at%. Good magnetostrictive characteristics, particularly at low magnetic fields, are achieved in both Sm-Fe and Sm-Fe-B thin films, although better properties are observed in B containing Sm-Fe thin films. At a magnetic field of 100 Oe, for example, the magnitude of magnetostriction is - 350 ppm in a Sm-Fe thin film and it is - 470 ppm in a B containing Sm-Fe thin film. With their excellent magnetostrictive characteristics, the present Sm-Fe and Sm-Fe-B thin films are considered to be suitable for Si based microdevices. (C) 1998 Published by Elsevier Science B.V.
