Electronic and magnetic structure of ultra-thin film of EuNiO3

ORAL

Abstract

In order to uncover the effect of reduced dimensionality on electronic and magnetic structure of rare earth nickelates series, we have investigate ultra thin film of EuNiO$_3$ (ENO) using hard and soft resonant x-ray scattering. Despite of such small thickness, it exhibits checker board type charge ordering, and E’ antiferromagnetic transition highlighting bulk-like electronic and magnetic structure can be retained for highly distorted member of $RE$NiO$_3$ family. The presence of charge ordering at room temperature also provides opportunity for their use in novel electric field controlled devices.
