Local metallic properties of LaNiO<sub>3</sub> detected using β-detected NMR
ORAL
Abstract
The rare earth nickelates (RNiO3) are a prototypical example of a metal-insulator transition in strongly correlated materials; LaNiO3 is the only RNiO3 that remains metallic .
Here, we will compare measurements on a single crystal and a thin film of LaNiO3 using β-detected NMR.
Analogous to μSR, β-NMR is a sensitive local probe of the electronic and magnetic properties of materials through the coupling between the 8Li nuclear spin and the electromagnetic properties of the host material and; therefore, provides a unique, local perspective.
We find clear evidence of metallic behaviour and no static magnetism.
However, the detailed account of the data appears inconsistent with the commonly considered distorted perovskite structure[1].
