Abstract: The effects of Ru underlayer on crystallographic structure, microstructures, and magnetic properties of Co72 Pt28 films were investigated. It was observed that Ru deposition pressure played a more important role in determining the crystallographic texture compared to Ru thickness. Ru had a preferred (0002) texture when deposited at low Ar pressure and induced perpendicular magnetic anisotropy for Co72 Pt28. However, at high Ar pressure, Ru (10 1- 0) and Ru (10 1- 1) peaks appeared that changed the easy axes of magnetization of Co72 Pt28 film from out-of-plane to in-plane directions. With increasing thickness of Ru top layer in the dual-layer structure of Ru underlayer, coercivities increased due to increased magnetic anisotropy and reduced intergranular magnetic interaction. © 2008 American Institute of Physics.
