This study presents systematic study of angle-resolved and polarization-resolved magneto-optical photoluminescence spectra of NiPS₃ in the Voigt geometry. We observed highly anisotropic, non-linear Zeeman splitting and polarization rotation of the Zhang-Rice exciton, which depends on the direction and intensity of the magnetic field and can be attributed to the spin-orbital coupling and field-induced spin reorientation. Furthermore, above the critical magnetic field, we detected additional splitting of the exciton peaks, indicating the coexistence of various orientations of NNature communications7841https://www.ebi.ac.uk/biostudies/studies/S-EPMC11380663biostudies-literatureManipulation of anisotropic Zhang-Rice exciton in NiPS₃ by magnetic field.PMC11380663Sun YJHu CPang SZhang JLv YGuan SLai JMWu BSong FChang HWang XJYuan ZfalseManipulation of anisotropic Zhang-Rice exciton in NiPS₃ by magnetic field.The effect of external magnetic fields on the behavior of the Zhang-Rice exciton in NiPS₃, which captures the physics of spin-orbital entanglement in 2D XY-type antiferromagnets, remains unclear.
