Strong carbon cage influence on the single molecule magnetism in Dy–Sc nitride clusterfullerenes

Magnetic properties of endohedral metallofullerenes with nitride clusters DySc(2)N and Dy(2)ScN and different carbon cages are studied by SQUID magnetometry. All molecules behave as single molecule magnets (SMMs) and exhibit magnetic hysteresis. It is found that the blocking temperature of magnetization and relaxation times strongly depend on the fullerene cage, with the C(80)-I(h) isomer offering the best SMM properties.
