Abstract

Polycrystalline samples of mixed alkali-metal fullerides, Rb_3-xK_xC₆₀ (x = 1, 2), were prepared by the direct reaction of C₆₀ with alkali metal vapor. Superconducting transition temperatures and lattice parameters, as determined by magnetic susceptibility and X-ray powder diffraction, are intermediate to the two endmembers, K₃C₆₀ and Rb₃C₆₀. Compounds appear to be solid solutions that obey Vegard's Law. No indication of size-difference-induced cation ordering on tetrahedral and octahedral sites is observed.
