Crystal Anisotropy Implications on the Magneto‐Optical Properties of van der Waals FePS 3

Ellenor Geraffy, K.N. Sharma, Shahar Zuri, Faris Horani et autres

ABSTRACT Antiferromagnetic FePS 3 has recently gained significant interest in its potential applications in spin‐related devices. Here, we show that in‐plane structural anisotropy has a major impact in shaping the optical responses of FePS 3 single‐crystals from the bulk form down to …

Evidence for Many-Body States in NiPS$_3$ Revealed by Angle-Resolved Photoelectron Spectroscopy

Miłosz Rybak, Benjamin Pestka, Biplab Bhattacharyya, Jeff Strasdas et autres

We present $μ$-ARPES spectra of the Mott-insulating van der Waals antiferromagnet NiPS$_3$. Signatures of strong correlations -- such as the onset of atomic or atomic-ligand multiplets and spin-orbit-entangled exciton have been observed in this material by various two-particle spectroscopies, but not previously …

Probing the Band Structure of the Strongly Correlated Antiferromagnet NiPS 3 across Its Phase Transition

Benjamin Pestka, Biplab Bhattacharyya, Miłosz Rybak, Jeff Strasdas et autres

NiPS 3 is an exfoliable van der Waals intralayer antiferromagnet with a zigzag-type spin arrangement. It is distinct from other TMPS 3 (TM: transition metal) materials by optical excitations into a strongly correlated state that is tied to the magnetic properties. However, …

Probing the band structure of the strongly correlated antiferromagnet NiPS3 across its phase transition

Benjamin Pestka, Biplab Bhattacharyya, Miłosz Rybak, Jeff Strasdas et autres

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 excitations into a strongly correlated state that is tied to the magnetic properties. However, the related, fundamental band structure …

Tunable Ultrastrong Magnon–Magnon Coupling Approaching the Deep-Strong Regime in a van der Waals Antiferromagnet

C. W. F. Freeman, Harry Youel, Adam K. Budniak, Zekun Xue et autres

Antiferromagnetic (AFM) magnons in van der Waals (vdW) materials offer substantial potential for applications in magnonics and spintronics. In this study, we demonstrate ultrastrong magnon-magnon coupling in the GHz regime within a vdW AFM, achieving a maximum coupling rate of 0.91. Our …

Imaging the Néel Vector in Few-Layer CrPS 4 with Second-Harmonic Generation

Yi Wei Ho, Ming‐Jun Chen, Magdalena Grzeszczyk, Adam K. Budniak et autres

Second-harmonic generation (SHG) is a powerful technique for probing the crystallographic symmetry. Recently, SHG has also been shown to exhibit sensitivity to time-reversal symmetry, allowing studies of magnetic order in layered antiferromagnetic (AFM) materials. Here, we report SHG investigation of chromium thiophosphate …

Direct Optical Probing of the Magnetic Properties of the Layered Antiferromagnet CrPS 4

Tomasz Fąs, Mateusz Wlazło, Magdalena Birowska, Miłosz Rybak et autres

Abstract The unusual magnetic properties of van der Waals‐type antiferromagnetic semiconductors such as transition metal thiophosphates make them highly attractive for spintronics and optoelectronics. However, a link between the magnetic and optical properties of these materials, required for practical applications, has not …

Identifying Band Structure Changes of FePS3 across the Antiferromagnetic Phase Transition

Benjamin Pestka, Jeff Strasdas, Gustav Bihlmayer, Adam K. Budniak et autres

Magnetic 2D materials enable interesting tuning options of magnetism. As an example, the van der Waals material FePS 3, a zig-zag-type intralayer antiferromagnet, exhibits very strong magnetoelastic coupling due to the different bond lengths along different ferromagnetic and antiferromagnetic coupling directions enabling …
