本文报道了一种居里温度T（c）= 16.1K的有机分子铁磁体[C60 TDAE 0.86; TDAE是四（二甲氨基）乙烯]的性质。铁磁状态不显示剩磁，并且低于T（c）的磁化强度的温度依赖性不遵循常规铁磁体的预期行为。这些结果被解释为一个三维系统导致软铁磁体的反射。
The properties of an organic molecular ferromagnet [C60TDAE0.86; TDAE is tetrakis(dimethylamino)ethylene] with a Curie temperature T(c) = 16.1 kelvin are described. The ferromagnetic state shows no remanence, and the temperature dependence of the magnetization below T(c) 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.
