Abstract

Ultrathin films of Co were deposited in situ on a well-prepared Pt(110) single-crystal surface and the induced magnetization of the Pt atoms at the interface was investigated with resonant magnetic surface x-ray-diffraction measurements at the L absorption edges of Pt. The measurements indicate that the magnetization of the Pt atoms extends to three atomic layers below the Co film and that a strong in-plane magnetic anisotropy exists. The easy direction of magnetization in the surface plane is perpendicular to the close-packed atomic rows in the Pt substrate.
