Magnetic relaxation investigations of Cu/Fe4 Sm/Cu multilayers from 20 K to 1.6 K at low and high fields have been performed. The constancy of both the magnetic viscosity and the coercive field below 2.5 K suggests that this temperature corresponds to the crossover between thermal and quantum regimes.
