Magnetic behavior and phase diagram of epitaxial Er3Fe5O12 thin films across the compensation temperature
Satakshi Pandey, Antoine Barbier, Anne Forget +6
Rare-earth iron garnet (RE3Fe5O12) films are promising insulating ferrimagnets. They can show low magnetic damping, perpendicular magnetic anisotropy, and ultrafast spin dynamics,…
Impact of Electron Correlations on Infinite-Layer Cuprates and Nickelates
Xunyang Hong, Yuetong Wu, Ying Chan +18
Optimization of unconventional superconductivity involves a balance of interaction strengths. Precise determination of correlation strength across different material families is th…
Spin and orbital excitations in undoped infinite layers: a comparison between superconducting PrNiO2 and insulating CaCuO2
Francesco Rosa, Hoshang Sahib, Giacomo Merzoni +9
Infinite-layer nickelates are among the most promising cuprate-akin superconductors, although relevant differences from copper oxides have been reported. Here, we present momentum-…
X-raying Mg0.2Co0.2Ni0.2Cu0.2Zn0.2O: disentangling elemental contributions in a prototypical high-entropy oxide
Maryia Zinouyeva, Martina Fracchia, Giulia Maranini +10
We employ several X-ray based techniques, including X-ray diffraction, absorption and resonant inelastic scattering, to disentangle the contributions of individual chemical species…
Magnetic Excitations of a Half-Filled Tl-based Cuprate
I. Biało, Q. Wang, J. Küspert +21
Strong electron correlations drive Mott insulator transitions. Yet, there exists no framework to classify Mott insulators by their degree of correlation. Cuprate superconductors, w…
Orbital mixing and strong Hund's coupling stabilize spin order in van der Waals ferromagnet CrI3
Alessandro De Vita, Srdjan Stavrić, Roberto Sant +8
Recent years have seen a vast increase in research into van der Waals magnetic materials. In many of these systems, magnetism is introduced via light 3d-transition metal elements,…
Temperature dependent Resonant X-ray Inelastic Scattering at Ni L3-edge for NaNiO2 and LiNiO2
Quentin Jacquet, Kurt Kummer, Marie Guignard +4
LiNiO2 is a promising cathode material for Li-ion battery but its atomic and electronic structure is under debate. Indeed, two sets of Ni-O distances are identified from local stru…
Coincident onset of charge order and pseudogap in a homogeneous high-temperature superconductor
D. Betto, S. Nakata, F. Pisani +10
Understanding high-temperature superconductivity in cuprates requires knowledge of the metallic phase it evolves from, particularly the pseudogap profoundly affecting the electroni…
The influence of phonon symmetry and electronic structure on the electron-phonon coupling momentum dependence in cuprates
Maryia Zinouyeva, Rolf Heid, Giacomo Merzoni +16
The experimental determination of the magnitude and momentum dependence of electron-phonon coupling (EPC) is an outstanding problem in condensed matter physics. The intensity of ph…
