摘要： 采用多靶磁控溅射仪在室温和衬底温度为300 ℃的条件下制备Tb/Fe/Dy纳米多层膜，研究其磁性能和超磁致伸缩性能.结果表明该纳米多层膜较TbDyFe单层膜有更明显的垂直磁各向异性和更大的矫顽力.尽管纳米多层膜样品具有垂直各向异性，但仍具有超磁致伸缩性能.特别是衬底温度为300 ℃的纳米多层膜样品，具有Laves相结构的TbDyFe纳米晶体析出，使得低磁场下磁致伸缩性能有了显著的提高.

Abstract: Tb/Fe/Dy nano-multilayer films were deposited by multi-targets magnetron sputtering system at room temperature and substrate temperature of 300 ℃. The nano-multilayer films have large perpendicular anisotropy and high coercive force than the TbDyFe single layer film, and show giant magnetostrictive effect though they have perpendicular anisotropy. The nano-multilayer film deposited by substrate temperature of 300 ℃ has enhanced low field giant magnetostrictive effect because the nano-crystalline of TbDyFe with Laves phase structure segregates from the amorphous matrix.

Key words: nano-mulitilayer films, giant magnetostrictive effect, perpendicular anisotropy, Tb/Fe/Dy, nano-mulitilayer films, giant magnetostrictive effect, perpendicular anisotropy
