Intrinsic localized magnetic moments in overdoped High- Tc cuprate (Tl 1- xPb x)Sr 2CaCu 2O 7 probed by 17O NMR
Abstract
In this paper we present the study of two overdoped compounds of the (Tl 1- xPb x)Sr 2CaCu 2O 7 system by 17O NMR. From the thermal variation of the 17O linewidth the presence of localized magnetic moments has been detected, these magnetic moments being located in the conducting CuO 2 planes. The comparison of the Curie constants deduced from NMR data for the overdoped sample ( Tc = 65K) and for the heavily overdoped sample ( Tc ≅ 0K) is discussed.
