Magnetic Excitations in Infinite-layer Nickelates

ORAL

Abstract

The discovery of superconductivity in infinite-layer nickelates sparks a substantial amount of interest due to its similarities of crystal structure and nominal d-orbital valence to cuprates. One of the central questions regards whether magnetic excitations exist in infinite-layer nickelates and to what extend does it resemble the magnetic excitations in cuprates. Here, we studied the magnetic excitations in infinite-layer nickelates by resonant inelastic x-ray scattering (RIXS) at the Ni L3-edge. Signatures of magnetic excitations have been resolved. The behaviors of these excitations, their doping dependence, and the comparison with the magnetic excitations in cuprates will be discussed.
