摘要：

Inelastic neutron scattering experiments performed on a single crystal of the antiferromagnetic compound Ce0.87La0.13Ru2Si2 under applied pressures of up to 5 kbar are reported. A quantum critical point is reached at around 2.6 kbar where long-range magnetic order disappears. The variation of the characteristic energy scales with respect to temperature and pressure is followed and found to saturate in the ordered phase.
