with thickness as observed with β-detected NMR

A unique set of electronic and structural conditions allow for high-T_c superconductivity in the cuprates.
It has been postulated that LaNiO₃/LaMO₃ (M = Al, Ti, Ga) superlattices (SLs) could share enough of these properties to support a related superconducting state[1].
LaNiO₃ is the only one of the rare-earth nickelates (RNiO₃) that remains a paramagnetic metal at all temperatures.
Here, we present β-detected NMR measurements on LaNiO₃/LaAlO₃ SLs.
Specifically, we will address the evolution of the metallic phase of LaNiO₃ with decreasing sample thickness.
