Abstract The EPR study of polycrystalline C 60 shows the evidence of a hydrostatic pressure effect (up to 700 MPa) on the g ‐value of intrinsic defects of polycrystalline C 60 , i.e. C + 60 . The pressure coefficient of the g ‐factor, (∂ g /∂ p ) T , has different values in both f.c.c. and s.c. phases of C 60 . This result is explained by the large compressibility of the fullerene lattice.
