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…
Doping evolution of spin excitations in LaSrNiO/SrLaAlO superconducting thin films
Hengyang Zhong, Bo Hao, Anni Chen +11
Ambient-pressure superconductivity in compressively strained bilayer nickelate films provides a unique platform to test pairing scenarios, yet the evolution of magnetism with carri…
Spin correlations in LaNiO thin films
Hengyang Zhong, Bo Hao, Zhijia Zhang +15
The discovery of ambient-pressure superconductivity with K in LaNiO (LNO) thin films grown on the SrLaAlO (SLAO) substrate with compressiv…
Ligand Mediated Magnetic Coupling Across Metamagnetic Transitions in CrPS4
Giuseppe Buccoliero, Rachel Nickel, Roberto Sant +8
Chromium thiophosphate (CrPS4) is a long-known material: a layered semiconducting antiferromagnet. Its recently discovered gate-tunable metamagnetic phase transitions, the remarkab…
Direct High-Magnetic-Field Coupling to Stripe Order in a Cuprate Superconductor
Leonardo Martinelli, Izabela BiaÅo, 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…
