Query: Reverse Monte Carlo and Rietveld modelling of BaMn(Fe,V)F7 glass
  structures from neutron data   Fluoride glasses BaMnMF7 (M = Fe, V, assuming isomorphous replacement) have
been structurally modelled. The neutron patterns were simulated by the reverse
Monte Carlo (RMC) and the Rietveld for disordered materials (RDM) methods. The
best fit is obtained from one of the seven tested crystalline models : the
BaMnGaF7 structure-type in which the glasses crystallize. However, by RMC
applied to enlarged RDM models, the difference between the best and the worst
fit is quite small (DRp ~ 0.5%), suggesting that two interference functions are
not enough for the characterization of such multicomponent glasses, or that the
average short and medium range order is similar in the seven models in spite of
strong differences in the polyhedra linkage.
