The synthesis of macroscopic amounts of C60 and C70 (fullerenes) has stimulated a variety of studies on their chemical and physical properties. We recently demonstrated that C60 and C70 become conductive when doped with alkali metals. Here we describe low-temperature studies of potassium-doped C60 both as films and bulk samples, and demonstrate that this material becomes superconducting. Superconductivity is demonstrated by microwave, resistivity and Meissner-effect measurements. Both polycrystalline powders and thin-film samples were studied. A thin film showed a resistance transition with an onset temperature of 16 K and essentially zero resistance near 5 K. Bulk samples showed a well-defined Meissner effect and magnetic-field-dependent m...
