Je. Schirber et al., EFFECT OF PRESSURE ON THE SUPERCONDUCTING PRIMITIVE CUBIC AND POLYMERIC PHASES OF NA2CSC60, Physica. C, Superconductivity, 260(3-4), 1996, pp. 173-176
The pressure dependence of the superconducting transition temperature,
T-c, has been determined using several gaseous pressure media and a v
ariety of pressure-temperature cycles, both of which profoundly affect
T-c. The orthorhombic ''polymer'' phase discussed by Zhu is found to
be superconducting. Models for the unexpected behavior are discussed.
