Evidence for Many-Body States in NiPS Revealed by Angle-Resolved Photoelectron Spectroscopy
MiÅosz Rybak, Benjamin Pestka, Biplab Bhattacharyya +11
We present -ARPES spectra of the Mott-insulating van der Waals antiferromagnet NiPS. Signatures of strong correlations -- such as the onset of atomic or atomic-ligand multi…

Robust spin splitting and fermiology in a layered altermagnet
Alessandro De Vita, Chiara Bigi, Davide Romanin +42
Altermagnetism defies conventional classifications of collinear magnetic phases, standing apart from ferromagnetism and antiferromagnetism with its unique combination of spin-depen…

Probing the band structure of the strongly correlated antiferromagnet NiPS3 across its phase transition
Benjamin Pestka, Biplab Bhattacharyya, Milosz Rybak +19
NiPS3 is an exfoliable van-der-Waals intralayer antiferromagnet with zigzag-type spin arrangement. It is distinct from other TMPS3 (TM: transition metal) materials by optical excit…
