The properties of an organic molecular ferromagnet [C(60)TDAE(0.86); TDAE is tetrakis(dimethylamino)ethylene] with a Curie temperature ;T(c) = 16.1 kelvin are described. ferromagnetic state shows no remanence, and the dependence magnetization below does not follow behavior expected conventional ferromagnet. These results interpreted as reflection three-dimensional system leading to soft
