Layer-Dependent Phonons, Excitons, and Magneto-Optical Phenomena in CrSBr: A Mini Review
Muhammad Aftab, Chinmay Kumar Mohanty, Zain Ashfaq +5
Two-dimensional layered magnetic materials offer a versatile platform for exploring low-dimensional magnetism and coupled many-body interactions in these materials. Chromium sulfur…
Manipulation of localized excitons in CrPS by temperature and magnetic field
Dipankar Jana, Swagata Acharya, Amit Pawbake +9
Layered van der Waals magnetic semiconductors provide a versatile platform for exploring excitonic phenomena intertwined with spin and lattice degrees of freedom, enabling excitons…
Spin-flip optical excitations in van der Waals antiferromagnet CrPS
Dipankar Jana, Aljoscha Soll, Zdenek Sofer +4
We investigate the near-infrared optical response of the semiconducting van der Waals antiferromagnet CrPS and identify previously unreported spin-entangled optical resonances.…
Resonant Raman scattering in bilayer 3R-MoS
Chinmay K. Mohanty, Kacper Walczyk, Tomasz Woźniak +5
Raman scattering is a powerful spectroscopic technique widely employed to investigate light-matter interactions and lattice dynamics in two-dimensional materials. Here, we investig…
Probing Dielectric Screening in van der Waals Heterostructures via Pressure-Tuned Exciton Rydberg Series
Shalini Badola, Adlen Smiri, Thomas Pelini +7
Excitons in two-dimensional semiconductors are directly exposed to the environment and are sensitive to the dielectric properties of their surrounding. Here, we show that the Rydbe…
Field-induced spin-flip and spin-flop transitions in NdFeO3
Mariana M. Gomes, Rui Vilarinho, E. Miranda +14
Magnetic control of correlated spin systems is central to the development of next-generation spin-based technologies. Rare-earth orthoferrites provide an interesting platform in wh…
Magnetic-field-induced magnon portfolio in a van der Waals magnet
T. Riccardi, F. Le Mardélé, L. A. Veyrat de Lachenal +12
Magnonic excitations are investigated in chromium oxychloride (CrOCl), a van der Waal (vdW) antiferromagnet prone to a multitude of magnetic phase transitions, with absorption expe…
Magnetic field tuning of modulated magnetic orders in CrOCl at the two-dimensional limit
T. Riccardi, A. Pawbake, S. Badola +9
Chromium oxychloride is a van der Waals magnet with intrinsic competing exchange interactions, including a strong antiferromagnetic one, source of a very rich magnetic phase diagra…
Room-temperature antiferromagnetic resonance in NaMnAs
Jan Dzian, Stáňa Tázlarů, Ivan Mohelský +16
We report on antiferromagnetic resonance experiments in bulk tetragonal NaMnAs -- a room-temperature antiferromagnetic semiconductor. Our results corroborate previous ab initio stu…
Interplay of Charge and Magnetic Orders in SmNiC Mediated by Electron-Phonon Interaction
A. von Ungern-Sternberg Schwark, A. -A. Haghighirad, R. Heid +11
We investigate the interplay between charge density wave (CDW) instabilities and ferromagnetism in SmNiC using diffuse and inelastic x-ray scattering together with Raman spectr…
Van der Waals CrSBr alloys with tunable magnetic and optical properties
Shalini Badola, Amit Pawbake, Bing Wu +4
Van der Waals magnets are attracting a lot of attention for their potential integration in spintronic and magnonic technologies. CrSBr is an A-type antiferromagnet that shows a cou…
