Decoupling of Static and Dynamic Charge Correlations revealed by Uniaxial Strain in a Cuprate Superconductor
L. Martinelli, I. Biało, X. Hong +17
We use uniaxial strain in combination with ultra-high-resolution Resonant Inelastic X-ray Scattering (RIXS) at the oxygen K- and copper L3-edges to study the excitations stemming f…
Emergence of interfacial magnetism in strongly-correlated nickelate-titanate superlattices
Teguh Citra Asmara, Robert J. Green, Andreas Suter +21
Strongly-correlated transition-metal oxides are widely known for their various exotic phenomena. This is exemplified by rare-earth nickelates such as LaNiO, which possess int…
Investigation of spin excitations and charge order in bulk crystals of the infinite-layer nickelate LaNiO
S. Hayashida, V. Sundaramurthy, P. Puphal +10
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 o…
The origin of magnetism in a supposedly nonmagnetic osmium oxide
S. Agrestini, F. Borgatti, P. Florio +16
A supposedly nonmagnetic 5d double perosvkite oxide is investigated by a combination of spectroscopic and theoretical methods, namely resonant inelastic X-ray scattering, X-ray…
Universal orbital and magnetic structures in infinite-layer nickelates
M. Rossi, H. Lu, K. Lee +17
We conducted a comparative study of the rare-earth infinite-layer nickelates films, RNiO2 (R = La, Pr, and Nd) using resonant inelastic X-ray scattering (RIXS). We found that the g…
Resolving the Orbital Character of Low-energy Excitations in Mott Insulator with Intermediate Spin-orbit Coupling
K. von Arx, P. Rothenbühler, Qisi Wang +10
Multi-band Mott insulators with moderate spin-orbit and Hund's coupling are key reference points for theoretical concept developments of correlated electron systems. The ruthenate…
Evolution of the magnetic excitations in electron-doped
X. T. Li, S. J. Tu, L. Chaix +13
We investigated the high energy spin excitations in electron-doped , a cuprate superconductor, by resonant inelastic x-ray scatter…
Detection of a two-phonon mode in a cuprate superconductor via polarimetric RIXS
Kirsty Scott, Elliot Kisiel, Flora Yakhou +15
Recent improvements in the energy resolution of resonant inelastic x-ray scattering experiments (RIXS) at the Cu-L edge have enabled the study of lattice, spin, and charge exci…
Quadrupolar magnetic excitations in an isotropic spin-1 antiferromagnet
A. Nag, A. Nocera, S. Agrestini +5
The microscopic origins of emergent behaviours in condensed matter systems are encoded in their excitations. In ordinary magnetic materials, single spin-flips give rise to collecti…
