Abstract

The magnetic properties of single crystal TDAE-C70-toluene are reported in relation to its unique dimerized structure of C70 molecules in the unit cell. The g-factor at room temperature (g = 2.0052) suggests that the origin of the magnetism is different from C70 (g = 2.002). The spins on the C70 molecules are cancelled out due to the dimerization. No magnetic phase transition appears at least down to 0.5 K. The magnetic susceptibility follows the Curie-Weiss law with the Weiss constant of +0.36 K. These results show that the weakly coupled spins on TDAE molecules contribute the magnetism of this salt, which is in contrast to the ferromagnetic TDAE-C60 where the TDAE spins are cancelled.
