摘要：

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 Ce0.925La0.075Ru2Si2 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.
