Abstract

We report results of X-ray diffractometry and magnetic measurements performed on Ag/Ni superlattices prepared by triode dc-sputtering. The X-ray results suggest structural coherence and interface sharpness whatever the thickness of the elemental layers with (111) textures for both Ag and Ni. Magnetization measurements confirm the existence of sharp interfaces. They also indicate that the magnetic moments preferentially lie in the plane of the layers whatever the Ag or Ni thicknesses. We also present evidence of the oscillatory character of the magnetic coupling of the Ni layers through the non-magnetic Ag layers, which correlates with both magnetoresistance and low-angle neutron diffraction experiments.
