We have synthesized superconductive and nonsuperconductive samples of the n-type high-(Formula presented) superconducting system (Formula presented)(Formula presented)(Formula presented) from the same batch. They give very similar normal state (Formula presented) NMR results, with decreasing spin-lattice relaxation time ((Formula presented)) and the spin-spin relaxation time ((Formula presented)) 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.
