摘要：

X-ray resonant magnetic scattering experiments using linear and circular polarised light have been caried out at the Ni and Fe L(2,3) absorption edges on magnetically coupled Ag/Ni and Ag/NiFe multilayers. The strong enhancement of the X-ray magnetic resonant scattering, especially at the Fe L edges, allows to evidence a superlattice magnetic peak due to the antiferromagnetic coupling between Ni or NiFe layers. Magnetic reflections represent several % of the intensity of the charge peak. With the magnetic moments aligned between layers, large changes (up to 75%) in the intensity of the chemical modulation peak have been observed upon reversal of the direction of the magnetic field. For the Ag/Ni, multilayer a detailed analysis gives a magnetic scattering amplitude equal to 8 r(o) per nickel atom.
