                      for x = 1. On the basis of the generalized density of phonon
                      states obtained by inelastic neutron scattering, the
                      vibrational entropy of the disordered defect fluorite
                      Ndinline imageZrinline imageOinline image is found to be
                      $12(3)\%$ smaller than the one of the ordered pyrochlore
                      counterpart. Accordingly, the loss of specific Zr–O
                      coordination in the defect fluorite structure leads to a
                      strong broadening of phonon modes. The Eu sublattice in both
                      structure types was further characterized by thermodynamic
                      quantities calculated using the Eu partial density of phonon
                      states. The Eu framework is shown to be significantly softer
                      than the other sublattices.},
