Fig. 2 — Coherent spin dynamics in transverse magnetic field. a Kerr rotation dynamics in CsPbBr₃ crystal at different magnetic fields. Magenta thick line for B_V = 0.25 T is fit to the experimental data with two decaying oscillatory functions (Methods). b Fast Fourier transform spectra of spin dynamics traces from a. c Magnetic field dependencies of electron (squares) and hole (circles) Larmor frequencies. Lines show linear fits to data. d Magnetic field dependencies of electron (squares) and hole (circles) spin dephasing times. Lines show reciprocal to B_V fits to data with evaluated spread of g-factors. a–d T = 10 K. e Temperature dependence of hole spin dephasing time. Line is fit with activation dependence having energy parameter ΔE = 14 meV. Source data are provided as a Source Data file
