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
