Vf. Masterov et al., THE METAL-INSULATOR-TRANSITION AND SUPERCONDUCTIVITY IN ALLOTROPES OFCARBON INTERCALATED WITH COPPER - PREDICTION AND EXPERIMENT, Fullerene science and technology, 6(3), 1998, pp. 481-497
The complex of studies carried out on CunC60 samples, including SQUID
and microwave measurements clearly support the existence of a supercon
ducting phase of Cu1,5C60 With T-c=120K. Heating a samples of pyroliti
c graphite intercalated with copper and oxygen above 77K initiates a M
etal-Insulator transition. We assume the same idea that the supercondu
cting transition temperature T-c in CunC60 samples changes near the M-
I transition.
