摘要：

We report neutron scattering experiments on single crystals of Ce1-xLaxRu2Si2 with x = 0 and x = 0.2. In CeRu 2Si2 the magnetic scattering is the superposition of two contributions: (i) a single site (q-independent) quasi-elastic contribution, and (ii) a strongly peaked inelastic contribution ascribed to magnetic correlations. The correlation lengths and the fluctuation rates of both contributions have been studied as a function of temperature. In Ce0.8La0.2Ru2Si2, the quasi-elastic neutron scattering measurements as a function of temperature show the coexistence of strong magnetic fluctuations at low temperature together with the incommensurate long range order. © 1990.
