Sb-5-mediated antiparallel Nd-Fe coupling in NdFeSb
S. Palazzese, Sh. Yamamoto, T. Kotte +15
We uncover the microscopic mechanism underlying the antiparallel Nd-Fe coupling in the intermetallic 4-3-5 compound NdFeSb by means of high-field x-ray magneti…
Paramagnon softening upon doping in oxychloride cuprate superconductors
Chafic Fawaz, Léo Gaspard, Laura Chaix +15
Understanding how magnetic excitations and exchange interactions evolve with doping is crucial for deciphering the physics that shapes the phase diagram of high-temperature cuprate…
Positive Temperature Coefficient of Anisotropy due to Groundstate in -FeO
Rachel Nickel, Kurt Kummer, Johan van Lierop
Positive anisotropy temperature coefficients () usually arise from hybridization between magnetic 3d states and strongly spin-orbit-coupled (SOC) subsystems. Yet -Fe$_2…
Machine-learning test of the single-ion model for excitations in cuprates
Maryia Zinouyeva, Leonardo Martinelli, Riccardo Arpaia +12
We investigate excitations in Resonant Inelastic X-ray Scattering spectra of YBaCuO and LaCuO using the local single-ion model. The data are analyzed by co…
Direct High-Magnetic-Field Coupling to Stripe Order in a Cuprate Superconductor
Leonardo Martinelli, Izabela Biało, Jens Oppliger +47
Superconductivity in cuprates emerges out of a complex normal state that hosts density waves, pseudogap physics, and strange metal properties. Here, we access this normal state by…
Contrasting Spin Excitations in Octahedral and Square-Planar n=8 Ruddlesden-Popper Nickelates
K. Scott, H. LaBollita, G. A. Pan +15
The discovery of superconductivity in reduced square-planar nickelates marked a major advance in identifying structural and electronic analogs to the high- cuprates. The more…
