摘要: An alkali-metal doping process through the thermal decomposition of alkali azides was applied to preparation binary-alloys doped C60. Usually we achieved a substantial improvement in superconducting volume fraction compared materials by standard gas-phase reaction. The other than sodium azide takes place liquid phase or melt, which is presumably responsible for more uniform and properties. For pure cesium sodium, however, no indication superconductivity has been detected so far. A systematic study on properties C60 with including Cs (Cs-Na, Cs-K, Cs-Rb) described previous results. In addition, similar via alkaline-earth found give nominal compositions Ba60C60 Sr6C60.
