We propose to use MARI to (1) compare the properties of the crystal field (CF) scheme between Yb2GaSbO7 (YGSO) and its parent compound Yb2Ti2O7, in hopes of elucidating the mechanism leading to the persistent fluctuations in YGSO as seen by Hodges et al. and (2) to deduce the CF scheme of Nd2GaSbO7 (NGSO) in hopes of providing a comparable CF scheme to its non-synthesised titanate analog. The work on MARI on both YGSO and NGSO represents an investigation concerning the effects of cationic disorder on the CF scheme of not only pyrochlores but frustrated systems in general and will represent a contribution to a growing amount of literature on such Bsite disorder explored through inelastic neutron scattering with prominent examples including Pr2-xBixRu2O7, Tb2Sn2-xTixO7 and most recently as seen with our work on MARI with CoV3O8.
