2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/26045We 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 $E/T^β$ can be plotted in a low temperature regime where the dynamical susceptibility is nearly temperature independent.4 pages, 4 figuresStrongly Correlated Electronstext
