Abstract
Inelastic neutron scattering experiments were performed to study the spin dynamics of the heavy fermion compound Ce0.925La0.075Ru2Si2. This composition corresponds to the borderline of the magnetic-non magnetic transition in the family of alloys Ce1 − x LaxRu2Si2. Short range magnetic correlations of an inelastic nature characterize this system in addition to a small ordered moment of the order of 0.02µB which appears below 2 K. Comparison with the magnetic excitation spectrum of the Pauli paramagnet CeRu2Si2 is given from the viewpoint of recent work on phase transitions near the magnetic instability point.
