Abstract: Investigations of temperature dependences of the magnetic susceptibility and dielectric perrmittivity in the temperature range 4.2 K < T < 300 K and the field dependence of the magnetization M(B) in fields B < 50 T show that the magnetic properties of the complex (ET)(2)C-60 cannot be described on the basis of the standard model, which assumes that the paramagnetic oxygen impurity makes the dominant contribution. It is found that the magnetism in (ET)(2)C-60 originates from the diamagnetic properties of the C-60 and ET molecules and specific paramagnetic centers of the C(60)(-)type. which are characterised by an anomalously low g factor \g\ similar to 0.14. First results for checking the oxygen paramagnetic center model for pure C-60 are reported.
