Simultaneous fitting of X-ray and neutron diffuse scattering data.
Conventional crystallographic refinement uses the Bragg-peak intensities and gives the single-site average crystal structure. Information about short-range order and local order is contained in the diffuse scattering that is distributed throughout reciprocal space. Models of the short-range order in materials can now be automatically refined. The complementarity of X-ray and neutron diffraction...
متن کاملSPINVERT: a program for refinement of paramagnetic diffuse scattering data.
We present a program (spinvert; http://spinvert.chem.ox.ac.uk) for refinement of magnetic diffuse scattering data for frustrated magnets, spin liquids, spin glasses, and other magnetically disordered materials. The approach uses reverse Monte Carlo refinement to fit a large configuration of spins to experimental powder neutron diffraction data. Despite fitting to spherically averaged data, this...
متن کاملDiffuse Scattering on Graphs
We formulate and analyze difference equations on graphs analogous to time-independentdiffusion equations arising in the study of diffuse scattering in continuous media.Moreover, we show how to construct solutions in the presence of weak scatterersfrom the solution to the homogeneous (background problem) using Born series, pro-viding necessary conditions for convergence and d...
متن کاملDiffuse multiple scattering
A new form of diffraction lines has been identified, similar to Rutherford, Kikuchi and Kossel lines. This paper highlights some of the properties of these lines and shows how they can be used to eliminate the need for sample/source matching in Lonsdale's triple convergent line method in lattice-parameter determination.
متن کاملX-Ray Diffuse Scattering
In this research program, modern x-ray scattering techniques are used to study the structures and phase transitions in novel states of condensed matter. We have two principal experimental facilities. At M.I.T. we have three high-resolution computer controlled x-ray spectrometers using either a conventional or high intensity rotating anode x-ray generator. The angular resolution can be made as f...
