The investigation of magnetic bistability in magnetic molecules has been the focus of intense research in our laboratory since the discovery of the first Single Molecule Magnet. The main source of the blocking of the magnetization at the single molecule level is magnetic anisotropy, which is here studied in detail. Though extremely large magnetic anisotropies can be encountered, in particular in lanthanide-based molecules, other mechanisms such as quantum tunneling and coupling to molecular vibrations need to be controlled to increase the temperature at which the magnetic memory of the molecules can be exploited.
Beyond the organization of these molecules on surfaces and their integration in spintronic devices, the laboratory is active in the investigation of the interplay of chirality and magnetism, as well as in the study of other types of bistable molecules, such as those exhibiting spin crossover behavior and redox isomerism.
