Je. Schirber et al., FULLERENE SUPERCONDUCTORS - PHASE-STABILITY AND ANOMALOUSLY LOW T(C)SIN SOME TERNARY COMPOUNDS, Journal of physics and chemistry of solids, 54(10), 1993, pp. 1427-1431
AC impedance and x-ray diffraction measurements versus temperature and
pressure on several ternary fullerene intercalation compounds are rep
orted. The results support our previously established empirical correl
ation between superconducting onset temperature and 300K fcc lattice c
onstant. Compounds which do not follow this correlation either phase s
eparate or are otherwise unstable at low T and/or high P.
