The expression for the diarnagnetic susceptibility derived using gauge invariant molecule orbital is applied to the calculation of π eletcrons of C60,C70,C76,C78,C82 and C84. The numerical results show that the fullerenes have large diarnagnetic susceptibility, and that the diarnagnetic susceptibility of some fullerenes, such as C70 and C76 etc., has remarkable anisotropy.
