X-ray study of the critical magnetic scattering in NpAs
Magnetic critical scattering has been observed by resonant-enhanced X-ray diffraction at the transition to the incommensurate antiferromagnetic phase of neptunium arsenide. The observed critical behaviour is significantly different from that observed with conventional neutron scattering techniques. The analysis suggests that the critical scattering is composed of two components, the sharper of which may be related to the surface or be a result of long-range order nucleated by impurities.
