Our previous neutron diffraction on C14 Laves phase compounds Nb1-xFe2+x revealed thata spin-density-wave (SDW) is masking an underlying ferromagnetic (FM) quantum critical point (QCP) of the system. With inelastic neutron scattering in a narrow Q range on an Fe-richsample we observed enhanced soft magnetic excitations. We propose to now carry out inelasticneutron scattering with high E resolution in a wide Q range on samples with chemical compositions covering the region in the phase diagram, where FM order is suppressed. This comprehensive data set will allow to discriminate between a magnetic excitation spectrum expected near a FM QCP and one influenced by an emerging SDW order masking the QCP. For this study we request 7 days of beam time on LET.
