摘要：

K-39 NMR signals from the orthorombic and tetrahedral sites are detected at high T, in K3C60. However below 210K a new K-39 line appears. Its characteristics are nearly identical to those found for the extra Rb-87 line observed below 400K in Rb3C60, which suggests that the low T structural and electronic properties of the superconducting A(3)C(60) compounds are quite similar. The T variations of the K-39 NMR shifts have been studied from the high T cubic phase down to the superconducting state. They are surprisingly found to be dominated by the variation of the orbital contributions.
