Artificial scaling laws of the dynamical magnetic susceptibility in heavy-fermion systems

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/Tβ can be plotted in a low temperature regime where the dynamical susceptibility is nearly temperature independent.
