Abstract：
The structures of [Ni ₇₀Co ₃₀(25A)/Cu(20A)] ₂₀multilayers were investigated by X-ray anomalous scattering technique. Different structural behaviors at the Cu/Ni ₇₀Co ₃₀and Ni ₇₀Co ₃₀/Cu interfaces were obtained respectively.For the as-deposited sample, the interfaces are asymmetrical. An 8A thick CuNi ₃and a 4A thick NiCo layers are observed at the Cu/Ni ₇₀Co ₃₀interface, however the Ni ₇₀Co ₃₀/Cu interface is sharp. For the annealed sample, the sharp Ni ₇₀Co ₃₀/Cu interface is replaced by a CuNi ₂Co sublayer of about 12A thick. The X-ray diffuse scattering experiments, performed with the incident X-ray energy close to the Co, Ni and Cu K edges respectively, show the distribution of Co, Ni and Cu at the interfaces is not uniform.
