We have recently discovered that Ce(Rh0.92Ru0.08)2Si2 is a unique example where the field-induced pseudo-metamagnetic (Hm) and antiferromagnetic (Hc) transitions are well-decoupled. We propose to characterize how the magnetic fluctuations evolve in the vicinity of Hm and Hc. By analogy with the parent compound CeRu2Si2, we expect that field-induced quantum criticality at the metamagnetic field Hm is controlled by the quenching of antiferromagnetic fluctuations combined with the development of critical ferromagnetic fluctuations in a narrow window around Hm. To test this hypothesis, we propose to perform an inelastic neutron scattering study on a single-crystal of Ce(Rh0.92Ru0.08)2Si2 using the triple-axis spectrometers IN14 or IN12 with a vertical magnet and a dilution fridge.
