The discovery of slow relaxation and quantum tunneling of the magnetization in the now so-called single molecule magnets (SMMs) two decades ago has inspired both physicists and chemists alike. This class of molecules has been expanded to heterometallic clusters incorporating transition metal and rare earth ions. The 4f ions were chosen because of their large angular momentum and magnetic anisotropy. Inelastic neutron scattering experiments were performed on the time-of-flight disk-chopper spectrometer IN6 at ILL on the SMM-series Mn2Ln2-squares with Ln=Y, Tb, Ho, Dy. Excellent data have been recorded, also for the Dy variety. The analysis of the data using a linked fit approach is presented.
