Abstract

The temperature dependences of the upper critical field Hc2(T) were measured over a broad range for both K3C60 and Rb3C60 superconductors. We found Hc2(0) to be 28 T for K3C60 and 38 T for Rb3C60 corresponding to the Ginzburg-Landau coherence length of 34 and 30. The H-T phase diagrams do not show qualitative difference from the behavior of a conventional type-II superconductor.
