Variable temperature EPR studies show that the CT-complexes of TDAE [ tetrakis (iV, N- dimethyl) -aminoethylene]-C_(60)(R_f)_n [R_f = C_3F_7, H(CF_2)_4] exhibit good stability and very high Curie temperature up to 190 K (16.1 K for TDAE-Cgo complex). It is possible that multi-radical anions may be formed during the complexation and the ordered array of their spins at relatively much higher Curie temperature may be the origin of the ferromagnetism for TDAE-C_(60) (R_f)_n.
