Extended Data Fig. 11: Powder XRD of polycrystalline target.
From: Linear-in-temperature resistivity for optimally superconducting (Nd,Sr)NiO2

Powder XRD of polycrystalline nickelate target with nominal stoichiometry of Nd0.825Sr0.175Ni1.15O3 (red), along with bulk powder XRD of Nd2NiO4 and NiO44,45. Aside from minor shifts in the peak positions due to chemical substitution of Sr, the observed peaks of the target are a superposition of Nd2NiO4 and NiO11.
