Figure 2: Characterization of relaxation times of a prototypical highly axial Dy(III) SMM. a) Relaxation profile arising from combined Orbach, Raman and QTM processes. And the electronic states involved (inset). b) Experimental (circles) and fitted (solid lines - Debye (green) and Generalized Debye (orange)) AC susceptibility components and associated Cole-Cole plots at variable temperature (inset). The \(\alpha\) parameter correlates with the error bars in the relaxation profile. c) top: Magnetization decays. Bottom left: energy diagram at initial and final times. Bottom right: Magnetization decay fitted with a single (green) and stretched (orange) exponential. The \(\beta\) parameter correlates with the error bars in the relaxation profile.
