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…
Room-temperature antiferromagnetic resonance in NaMnAs
Jan Dzian, StáÅa 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…
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…
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 +10
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…
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…
