A recent neutron study of a powder sample attests a splayed ferromagnetic structure for Yb2Ti2O7. However in the same work the authors report gapless magnetic excitations even though a Hamiltonian deduced from spin wave excitations under applied magnetic fields supports gapped excitations and a ferromagnetic ground state. Given that the obtained magnetic order parameter in this sample strangely does not respond to the sharp heat capacity anomaly, questions about the quality of this sample as well as the interpretation of gapless magnetic excitations as a universal feature for the Yb based pyrochlores have been raised. We believe we have obtained a proper sample that can be used to resolve huge controversy regarding magnetic excitations of Yb2Ti2O7 at low temperatures by inelastic neutron scattering in LET. For comparison, we propose also the same study on a mysterious sibling, Yb2Ir2O7.
