摘要：
Compelling evidence for band-type conductivity and even bulk superconductivity below T-c approximate to 8 K has been found in Ga-69,Ga-71 NMR experiments in crystalline ordered, giant Ga-84 cluster compounds. This material appears to represent the first realization of a theoretical model proposed by Friedel in 1992 for superconductivity in ordered arrays of weakly coupled, identical metal nanoparticles.
