Anomalous Behavior of the Ni${}^{1+}$ moment and interstitial band in bi-infinite-layered La${}_3$Ni${}_2$O${}_5$F

Young-Joon Song, W. E. Pickett, K. -W. Lee

The discovery of superconductivity in hole-doped Ni${}^{1+}$ systems with "infinite layer" NiO${}_2$ square-lattices analogous to the Cu${}^{2+}$ CaCuO${}_2$ cuprate has renewed conflictin…
