Abstract
The discovery of ferromagnetism in (TDAE)C60, Where TDAE is the tertia ry amine tetrakis(dimethylamino)ethylene, stimulated us to search for other amines, namely diazabicyclononene and diazabicycloundecene, whic h like TDAE lead to magnetic fullerides. Three tertiary amines were in vestigated. The doping process was studied in detail by in situ EPR an d absorption spectroscopy (UV/VIS/NIR). A complex reaction behaviour h as been observed. Studies of EPR and AC-susceptibility in the solid st ate show in all three cases pronounced magnetic correlations up to 80 K.
