Magnetic properties of the fullerene organic compounds in strong magnetic fields

Abstract Magnetisation study of the C 60 ·TMTSF·2CS 2 molecular complex in magnetic field up to 47 T for the temperature range 1.8–300 K and ESR spectroscopy of the molecular complex (ET) 2 C 60 at T =1.8 K for the frequency range 60–90 GHz in magnetic field up to 32 T provide the experimental evidence that a paramagnetic centers with the reduced g -factor values g g -factor values may be caused by dynamic Jan-Teller effect on the negative C 60 ions, which appear as defects in crystalline structure with a weak charge transfer.
