Abstract
A detailed study of the supercurrent flow in K3C60 single crystals is presented. From dc magnetization and ac susceptibility measurements we obtain the sample dimension over which the superconducting currents flow. We find that this dimension is identical to the sample size and, therefore, demonstrates the bulk nature of superconductivity in fullerenes in an unambiguous way.
