Abstract
Polarization analysis of the nonresonant magnetic x-ray scattering fro m the simple type-IA double-k antiferromagnet uranium arsenide has pro vided an experimental verification of the nonresonant magnetic x-ray c ross section and has shown the dominance of the orbital contribution t o the magnetization density. The measured value for the ratio of the o rbital to the spin contributions is in reasonable agreement with the f ree-ion value for a 5f(3) configuration.
