Low energy spin dynamics of the stoichiometric heavy fermion CeRuSn3
Abstract: Heavy fermion systems situated close to a quantum critical point present very rich physics due to the dominant Kondo interactions. Our investigations on the Kondo lattice heavy fermion CeRuSn3 reveals evidence of an untuned quantum criticality where the physics is governed by Griffiths singularities. The magnetization, magnetic susceptibility and heat capacity show clear power-law behavior indicating the formation of quantum Griffiths phase. The divergence of magnetic Grüneisen ratio and time-field scaling of longitudinal field µSR data reveals close proximity to a clean quantum critical point. Further investigations of untuned quantum criticality in stoichiometric CeRuSn3 by low energy spin dynamics study of E/T scaling would be very informative. We therefore propose to carry out E/T scaling study using low energy inelastic neutron scattering measurements on the OSIRIS spectrometer.
