Abstract

We present magnetization studies of a novel S=6 single molecule magnet (SMM) [Net4]3[Mn3Zn2(salox)3O(N3)6Br2] (Mn3). The results reveal extremely clean changes in the magnetization associated to the high crystalline quality of the compound. The sample allows a detailed study of the role of molecular symmetry on the nature of the magnetic quantum tunneling relaxation of these molecules. Experiments at temperatures down to 30 mK carried out in a 3D vector superconducting magnet will be presented. The possible role of phonons as originators of the tunneling relaxation of the magnetization in this SMM will be used to explain interesting experimental observations.
