NMR of Rare Isotope 43Ca in HTSC Tl2Ba2CaCu2O8
The electronic and crystal structure of HTSC thallium-based compounds is intensively investigated now. NMR is one of the most useful means of studying the nature of superconductivity. There are many papers devoted to 203;205Tl and 63;65Cu NMR in these compounds, which contain very useful information about their electronic structure. Other magnetic nuclei such as 17O and 43Ca could be also interesting for NMR investigations of these compounds, but their natural abundances are very low.
