NMR Evidence of Antiferromagnetic Spin Fluctuations in Nd${}_{0.85}$Sr${}_{0.15}$NiO${}_2$

Abstract

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 low temperatures. The spin-lattice relaxation rate $1{/}^1{T}_1$ is strongly enhanced when lowering the temperature, developing a broad peak at about 40 K, then decreases following a spin-wave-like behavior $1{/}^1{T}_1\sim T^2$ at lower temperatures. These results evidence a short-range glassy antiferromagnetic ordering of magnetic moments below 40 K and dominant antiferromagnetic fluctuations extending to much higher temperatures. Our findings reveal the strong electron correlations in bulk Nd${}_{0.85}$Sr${}_{0.15}$NiO${}_2$, and shed light on the mechanism of superconductivity observed in films of nickelates.
