Title: Phase engineering of rare earth nickelates by digital synthesis

Abstract

Here, we report on the electronic and magnetic properties of a series of [m EuNiO 3/p LaNiO 3] superlattices (thickness m and/or p = 1 unit cell) epitaxially grown on single crystalline NdGaO 3 substrates. The structural symmetry of these films has been investigated by the combination of in-situ reflection high energy electron diffraction and X-ray diffraction measurements. The metal-insulator transition and the magnetic transition temperatures of the short-period superlattices with m ≥ p are modified from the corresponding bulk Eu 1–xLa xNiO 3 (x=$$\frac{p}{m+p}$$ ) composition. In contrast to the corresponding bulk doped compound with x = 0.67, the [1 EuNiO 3/2 LaNiO 3] film remains metallic down to at least 2 K without signs of electronic or magnetic transitions. These findings demonstrate the power of the digital synthesis approach to realize electronic and magnetic phases of perovskite nickelates, unattainable in bulk.
