      abstract     = {Nd-based pyrochlore oxides of the form Nd2B2O7 have
                      garnered a significant amount of interest owing to the
                      moment fragmentation physics observed in Nd2Zr2O7 and
                      speculated in Nd2Hf2O7. Notably this phenomenon is not
                      ubiquitous in this family, as it is absent in Nd2Sn2O7,
                      which features a smaller ionic radius on the B site. Here,
                      we explore the necessary conditions for moment fragmentation
                      in the Nd pyrochlore family through a detailed study of the
                      mixed B-site pyrochlore Nd2GaSbO7. The B site of this system
                      is characterized by significant disorder and an extremely
                      small average ionic radius. Similarly to Nd2Sn2O7, we find
                      no evidence for moment fragmentation through our bulk
                      characterization and neutron scattering experiments,
                      indicating that chemical pressure (and not necessarily the
                      B-site disorder) plays a key role in the presence or absence
                      of this phenomenon in this material family. Surprisingly,
                      the presence of significant B-site disorder in Nd2GaSbO7
                      does not generate a spin-glass ground state and instead the
                      same all-in-all-out magnetic order identified in other Nd
                      pyrochlores is found here.},
