RIXS study on La-based infinite-layer nickelates

ORAL

Abstract

The recent discovery of superconducting nickelates has drawn significant interest in the field. Superconductivity was first discovered in the Nd-based infinite-layer nickelates. Soon, superconductivity was confirmed also in the La- and Pr-based infinite layer nickelates. Uncovering how the electronic structure varies between different rare-earth families of compounds could provide further information about the underlying microscopic mechanism. Recently, resonant inelastic x-ray scattering (RIXS) has revealed the electronic and magnetic excitations in the Nd-based infinite-layer nickelates. In this talk, we will present the RIXS results of the La-based infinite-layer nickelates, discuss the underlying elementary excitations, symmetry-broken states, and their comparisons with those in Nd-based compounds.
