摘要
Polarization analysis of the diffuse neutron scattering from a single-domain crystal of Mn-10 at. % Cu has been used to separate the scattering from a nonrandom distribution of Cu and Mn atoms and the magnetic scattering from perturbations of Mn magnetic moments. The technique has also allowed unambiguous discrimination between the longitudinal and transverse components of the magnetic defect scattering. Measurements were performed in extended regions of both the (100) and (11OBAR) planes at 5 K. The transverse component of the Mn magnetic defect is found to be long ranged and the Mn and Cu atoms strongly cluster on the face-centered-tetragonal lattice.
