Effects of oblique deposition on magnetostrictive characteristics of TbFe2 films formed by ion plating

The effects of oblique deposition to induce high magnetostrictive susceptibility and huge magnetostriction were studied. The giant magnetostrictive Tb-Fe films were prepared by an ion plating process with inclined vapor flux using substrates angled with 0, 30 and 60°. Increasing the substrate angle induced strongly in-plane magnetic anisotropy by the oblique deposition. The magnetic and magnetostrictive characteristics of Tb-Fe films were effected by an oblique anisotropy. The oblique anisotropy of Tb-Fe film may be induced by the shape anisotropy connected with columnar grain.
