Organic molecular soft ferromagnetism in a fullerene C60
Abstract
The properties of an organic molecular ferromagnet, C60 TDAE(0.86) TDAE is tetrakis(dimethylamino-ethylene) with a Curie temperature Tc = 16.1 K are described. The ferromagnetic state shows no remanence, and the temperature dependence of the magnetization below Tc does not follow the behavior expected of a conventional ferromagnet. These results are interpreted as a reflection of a three-dimensional system leading to a soft ferromagnet.
