We have synthesized superconductive and nonsuperconductive samples of the n-type high-Tc superconducting system Nd2CuO4-xFy from the same batch. They give very similar normal state 19F NMR results, with decreasing spin-lattice relaxation time (T1) and the spin-spin relaxation time (T2E) and increasing negative line shift on decreasing temperature. Our results seem to indicate that the fluorine is more likely to be substituted into the O(2) sites between the Nd planes in this system.
