Abstract

A method for making a superconducting fullerine composition, includes reacting a fullerine with an alloy, and particularly reacting C(60) with a binary alloy including an alkali metal or a tertiary alloy including two alkali metals in the vapor phase. Also, a Cesium-doped fullerine high T(c) superconducting composition has the formula Cs(x) C(60), and particularly Cs(3) C(60). Also, a homogeneous bulk single phase high T(c) superconducting composition has the formula (Rb(x) K(1-x))(3) C(60).
