Molecular nanomagnets represent quite promising systems for high-density storage devices and as building units in quantum computers. Key requirements for their large-scale industrial application are the storage efficiency and the storage reliability against internal and external perturbations.Indeed, the main source of memory loss results from electronic quantum fluctuations within the ground state of the molecule (so-called quantum tunneling). A Danish-based team of international researchers has now gauged the effect of a chemistry-induced symmetry change in lanthanides-based molecular nanomagnets, thus addressing both key requirements at once. The results, achieved via inelastic neutron scattering at the MLZ time-of-flight spectrometer TOFTOF and complementary techniques, recently appeared in Nature Communications and Advanced Functional Materials.
