Hyperfine interaction of electrons and holes with nuclei probed by optical orientation in methylammonium lead iodide perovskite crystals (opens in new tab)

Author(s): Mladen Kotur, Nataliia E. Kopteva, Dmitri R. Yakovlev, Bekir Turedi, Maksym V. Kovalenko, and Manfred BayerOptical orientation of electron and hole spins by circularly polarized light is investigated for ${\mathrm{MAPbI}}_{3}$ single crystals. The Hanle and polarization recovery effects measured in transverse and longitudinal magnetic fields, respectively, evidence the hyperfine interaction with nuclear …[Phys. Rev.
