Abstract

By intercalating large (Formula presented) molecules between the (Formula presented)(Formula presented) layers in (Formula presented)(Formula presented)(Formula presented)(Formula presented), the distance between the (Formula presented) blocks was significantly extended up to 7.2 Å. The superconducting properties of this system were measured in various magnetic fields applied perpendicular to the (Formula presented) planes. This system showed large positional fluctuation of the vortex even far below the transition temperature due to the reduction of dimensionality. The change of the thermodynamic parameters is well explained by the model of Josephson-coupled superconductivity. However, the interlayer coupling strength did not change the transition temperature drastically, which does not support the suggestion of Wheatley, Hsu, and Anderson of coherent hopping of the valence bond pair between the (Formula presented) layers.
