Description
The low-temperature thermal expansion of the heavy-fermion system with the formula Ce1-xLaxRu2Si2 (x=0 and x=0.05) close to the magnetic instability is analysed in terms of the renormalization group and self-consistent renormalized spin-fluctuation models. The Grueneisen parameter calculated using the renormalized Fermi temperature is compared with the effective one which is determined from thermal expansion measurements and previously obtained specific heat data.
