Despite the recent discovery of superconductivity in Nd 1 − x Sr x NiO 2 thin films, the absence of superconductivity and antiferromagnetism in their bulk materials remain a puzzle. Here we report the 1 H NMR measurements on powdered Nd 0 . 85 Sr 0 . 15 NiO 2 samples by taking advantage of the enriched proton concentration after hydrogen annealing. We find a large full width at half maximum of the spectrum, which keeps increasing with decreasing the temperature and exhibits an upturn behavior at…

It is shown that the NiO_{2} layers fall inside a critical region where the large pd hybridization favors a singlet ^{1}A_{1} hole-doped state like in CuO_2, thus a magnon "glue" is very unlikely and another mechanism needs to be found.
