重费米子化合物CeRu_2Si_2的非弹性中子散射表明，除了已有的k_1 =0.3a ~* 和k_2 =0.3（a ~*+B ~*）外，还存在一个调制矢量为k_3 =0.35c ~* 的反铁磁涨落.波数k3与Ce（Ru 1 −xRhx）2Si 2中出现的磁性长程有序有关。
Inelastic neutron scattering on the heavy fermion compound CeRu2Si2shows that there is an antiferromagnetic fluctuation with a modulation vector k3=0.35c* in addition to those with k1=0.3a* and k2=0.3(a*+b*) reported in the previous study. The wave number k3is associated with the magnetic long-range-order appearing in Ce(Ru1−xRhx)2Si2.
