Investigation of spin excitations and charge order in bulk crystals of
the infinite-layer nickelate LaNiO$_2$
Recent x-ray spectroscopic studies have revealed spin excitations and charge density waves in thin films of infinite-layer (IL) nickelates. However, clarifying whether the origin of these phenomena is intrinsic to the material class or attributable to impurity phases in the films has presented a major challenge. Here we utilize topotactic …
