Resonant cooling of nuclear spins by optically-oriented holes in MAPbI perovskite crystals
Mladen Kotur, Dmitri R. Yakovlev, Nataliia E. Kopteva +3
Resonant cooling of nuclear spins by photogenerated spin-oriented holes is demonstrated for MAPbI perovskite crystals. It is evidenced by Hanle-effect measurements under helici…
Bright-dark exciton splitting in lead halide perovskite crystals accessed via quantum beats in photon echoes
M. Alex Hollberg, Mikhail O. Nestoklon, Artur V. Trifonov +7
Understanding the fine structure of excitons is crucial for optoelectronic and quantum photonic applications of lead halide perovskites. It is demonstrated that polarization-sensit…
Hyperfine interaction of electrons and holes with nuclei probed by optical orientation in MAPbI perovskite crystals
Mladen Kotur, Nataliia E. Kopteva, Dmitri R. Yakovlev +3
Optical orientation of electron and hole spins by circularly polarized light is investigated for MAPbI single crystals. The Hanle and polarization recovery effects measured in…
Millisecond spin coherence of electrons in semiconducting perovskites revealed by spin mode locking
Sergey R. Meliakov, Evgeny A. Zhukov, Vasilii V. Belykh +4
Long spin coherence times of carriers are essential for implementing quantum technologies using semiconductor devices for which, however, a possible obstacle is spin relaxation. Fo…
Spin-dependent Raman and Brillouin light scattering on excitons in CsPbBr perovskite crystals
Ina V. Kalitukha, Victor F. Sapega, Dmitri R. Yakovlev +5
The spin properties of excitons and charge carriers in CsPbBr lead halide perovskite crystals are investigated by spin-dependent light scattering in magnetic fields up to 10 T.…
Magnetic switching of exciton lifetime in CrSBr
Ina V. Kalitukha, Ilya A. Akimov, Mikhail O. Nestoklon +13
Exciton dynamics in layered magnetic semiconductors provide a sensitive probe of the interplay between spin order and light-matter interaction. Here, we study thin CrSBr layers usi…
