摘要：
C60.TDAE (TDAE = tetrakis(dimethylamino)ethylene) with a T(c) of approximately 16K is probably the best example of an organic molecular ferromagnet known to date. Based on ESR studies, we demonstrate that C60.TDAE is a quasi one-dimensional spin one-half Heisenberg ferromagnet, with the C60 units being entirely responsible for the magnetism. C60-C60 interactions responsible for superconductivity in alkali metal doped C60 seem to be essential for the magnetism of C60.TDAE as well.
