Evidence for Many-Body States in NiPS Revealed by Angle-Resolved Photoelectron Spectroscopy
Miłosz 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 multip…

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…

Identifying band structure changes of FePS3 across the antiferromagnetic phase transition
Benjamin Pestka, Jeff Strasdas, Gustav Bihlmayer +16
Magnetic 2D materials enable novel tuning options of magnetism. As an example, the van der Waals material FePS3, a zigzag-type intralayer antiferromagnet, exhibits very strong magn…
