Revealing microscopic behaviors in strained infinite-layer nickelate membrane via RIXS with in-situ tunable strain

Exploring infinite-layer nickelate properties is a topic of current interest. Our initial measurements unveiled strain-induced XAS dichroism, indicating significant electronic structure modification. We propose to perform Ni L3-edge RIXS on free-standing, strained nickelate membranes to investigate orbital, magnon, and phonon evolution. These findings will deepen our understanding of nickelate electronic structure and serve as a milestone for RIXS studies on strained quantum material membranes.
