摘要：

X-ray resonant magnetic scattering experiments using linear and circular polarized light were performed at the Ni L(2,3) absorption edges on a Ag/Ni multilayer. A superlattice magnetic peak, due to the antiferromagnetic coupling between Ni layers, is evidenced. In the case of a ferromagnetic coupling, large changes in the charge peak (up to 15%) are observed upon reversal of the direction of the magnetic field. The magnetic scattering amplitude is evaluated to sro per nickel atom. Sum rules have been applied for the first time to the energy-dependent magnetic amplitude.
