      abstract     = {The question of structural disorder and its effects on
                      magnetism is relevant to a number of spin liquid candidate
                      materials. Although commonly thought of as a route to spin
                      glass behaviour, here we describe a system in which the
                      structural disorder results in long-range antiferromagnetic
                      order due to local symmetry breaking. Nd2ScNbO7 is shown to
                      have a dispersionless gapped excitation observed in other
                      neodymium pyrochlores below TN = 0.37 K through polarized
                      and inelastic neutron scattering. However the dispersing
                      spin waves are not observed. This excited mode is shown to
                      occur in only $14(2)\%$ of the neodymium ions through
                      spectroscopy and is consistent with total scattering
                      measurements as well as the magnitude of the dynamic moment
                      0.26(2) μB. The remaining magnetic species order completely
                      into the all-in all-out Ising antiferromagnetic structure.
                      This can be seen as a result of local symmetry breaking due
                      disordered Sc+3 and Nb+5 ions about the A-site. From this
                      work, it has been established that B-site disorder restores
                      the dipole-like behaviour of the Nd+3 ions compared to the
                      Nd2B2O7 parent series.},
