Abstract

An anomalous Cu NMR signal with extremely small e²qQ has been observed in the oxide superconductor Nd_1.85Ce_0.15 CuO_4-y The Knight shift decreased significantly as temperature decreased below T_c The temperature-independent T₁ of ⁶³Cu suggests that the relaxation is dominated by the fluctuation of the Nd-moment, and no magnetic order is achieved for this content of Ce.
