Abstract

Magnetic properties of endohedral metallofullerenes with nitride clusters DySc₂N and Dy₂ScN 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 C₈₀-I_h isomer offering the best SMM properties.
