摘要：

Inelastic neutron scattering studies of CeRu2Si2 under high magnetic field are reported. The dynamic short-range antiferromagnetic correlations are progressively replaced by static long-range ferromagnetic order when the field is increased. A simple interpretation using a phenomenological model leads to the conclusion I:hat the exchange interactions are field dependent and that their weight is shifted from the antiferromagnetic point to the ferromagnetic point as the field changes.
