Magnetic properties of C60 and C70 complexes with tetrakis (dimethylamino) ethylene (TDAE) have been studied by Faraday-balance magnetization and ESR measurements. It has been confirmed that TDAE-C60 possesses about one radical spin per molecule and shows a ferromagnetic-type transition at Tc=16.7-17.5 K. The appearance of a new broad and intense ESR signal below Tc suggests that the radical spins in the magnetically ordered state localize on each C60 molecule and are ferromagnetically correlated. On the contrary, TDAE-C70 demonstrates the usual Curie-type narrow ESR peak at all temperatures suggesting the absence of a ferromagnetic transition at least down to 4.5 K.
