Synthesis and Properties of La${}_{1-x}$Sr${}_x$NiO${}_3$ and La${}_{1-x}$Sr${}_x$NiO${}_2$

Abstract

Superconductivity has been realized in films of La${}_{1-x}$Sr${}_x$NiO${}_2$. Here we report synthesis and characterization of polycrystalline samples of La${}_{1-x}$Sr${}_x$NiO${}_3$ and La${}_{1-x}$Sr${}_x$NiO${}_2$ ($0\le x\le 0.2$). Magnetization and resistivity measurements reveal that La${}_{1-x}$Sr${}_x$NiO${}_3$ are paramagnetic metals and La${}_{1-x}$Sr${}_x$NiO${}_2$ exhibit insulating behavior. Superconductivity is not detected in bulk samples of La${}_{1-x}$Sr${}_x$NiO${}_2$. The absence of superconductivity in bulk La${}_{1-x}$Sr${}_x$NiO${}_2$ may be due to the generation of hydroxide during reduction or a small amount of nickel impurities. The effect of interface in films of La${}_{1-x}$Sr${}_x$NiO${}_2$ may also play a role for superconductivity.
