摘要：
As a first step of a study of the electronic properties Of CuO2 planes by probing calcium nuclei in the Bi-based high-Tc materials, we report here the structural assignment of Ca NMR lines measured in Ca-43-enriched powders of n=2 ((Bi,Pb)2Sr2CaCu2O8+x) and n-3 ((Bi,Pb)2Sr2Ca2Cu3O10+x) bismuth compounds. For the main calcium site (Ca between two CuO2 planes) we could determine the quadrupolar as well as the shift parameters.
