Results of high-energy magnetic X-ray diffraction for photon energies up to 500 keV are presented and the form of the magnetic scattering cross-section for relativistic energies is discussed. At 300 keV we experimentally proved that the scattering from the spin component perpendicular to the scattering plane is dominant. Within our statistical and systematic errors, the magnetic scattering amplitude for this component does not exhibit any variation with energy between 100 and 500 keV.
