%0 Journal Article %T Artificial scaling laws of the dynamical magnetic susceptibility in heavy-fermion systems %A W. Knafo %A S. Raymond %J Physics %D 2005 %I arXiv %R 10.1016/j.physleta.2005.04.041 %X We report here how artificial, thus erroneous, scaling laws of the dynamical magnetic susceptibility can be obtained when data are not treated carefully. We consider the example of the heavy-fermion system Ce$_{0.925}$La$_{0.075}$Ru$_{2}$Si$_{2}$ and we explain how different kinds of artificial scaling laws in $E/T^\beta$ can be plotted in a low temperature regime where the dynamical susceptibility is nearly temperature independent. %U http://arxiv.org/abs/cond-mat/0503410v1
