Fig. 3: Spin-flip Raman scattering of CsPbBr3.

a SFRS spectra measured in the Faraday (blue) and Voigt (red) geometries at T = 1.6 K. The excitation/detection polarization is σ−/σ+. Spectra are shown for the anti-Stokes spectral range where photoluminescence is suppressed. b Magnetic field dependence of the electron (purple squares) and hole (green circles) Stokes Raman shifts. Lines are linear fits with gF,e = + 2.06 and gF,h = + 0.65. c Angular dependences of the electron and hole g-factors for the magnetic field rotated in the Faraday-Voigt plane (φ = 0∘). Lines are fits using Eq. (4). The sample c-axis is oriented perpendicular to k and parallel to the x-axis, c∥B, corresponding to the Voigt geometry (θ = 90∘).
