Magnetic Memory Effect in a Transuranic Mononuclear Complex
Molecular nanomagnets that display magnetic bistability are the subject of intensive investigation due to their unique potential in ultrahigh-density memory components and spintronic devices.[1] So far, the best practical realization of such single-molecule magnets (SMMs) are polymetallic transition-metal complexes with strong intramolecular exchange coupling, giving rise to a high-spin ground state and negligible intercluster interactions.[2] However, 3d metals
are restricted by their comparatively low anisotropy, and SMMs with better performance could be produced by exploiting the higher single-ion anisotropy typical of felectron ions.[3] This possibility has been practically demonstrated
by Ishikawa et al., who discovered that mononuclear rare earth metal bis-phthalocyanine compounds (Pc2RE) display magnetic hysteresis under favorable conditions
