Abstract
We describe a model-independent approach for the extraction of spin-wave dispersion curves from neutron total scattering data. The method utilises a statistical analysis of real-space spin configurations to calculate spin-dynamical quantities. The RMCProfile implementation of the reverse Monte Carlo refinement process is used to generate a large ensemble of supercell spin configurations from powder diffraction data. Our analysis of these configurations gives spin-wave dispersion curves that agree well with those determined independently using neutron triple-axis spectroscopic techniques.
