Abstract Scope |
A model-free program for analyzing the diffuse scattering of single crystals due to magnetic disorder is showcased. The recently developed program for users of single crystal diffraction instruments at Oak Ridge National Laboratory is capable of extracting real-space magnetic moment correlations from neutron diffraction experiments. In particular, the high quality instruments provide a wide range of sample environments that enable the study of short range ordering in magnetic materials under high and low temperatures, pressures, and magnetic fields. An example of a refinement is shown with iron manganese oxide mineral bixbyite which is a geometrically frustrated antiferromagnetic crystal. The optimized program is fast and user-friendly allowing users to efficiently characterize the underlying disordered structures of magnetic crystals ultimately aiding in the development of emerging and advanced magnetic materials. |
