Abstract
The functional dependence of the superconducting transition temperature Tc on the electronic density of states N(Ef) was determined for Rb3C60 by measuring the magnetic susceptibility under hydrostatic pressure to ∼ 1 GPa in a commercial SQUID magnetometer. Both Tc and N(Ef) decrease under pressure at the rates -31%/GPa and -14.5%/GPa, respectively, but lie above the corresponding values for K3C60 at the same lattice parameter. The present results are consistent with weak-coupling BCS theory with characteristic energy EcharkB≈320−810 K.
