dc.description.abstract
The versatile potential of lead halide perovskites and two-dimensional materials is merged in the Ruddlesden–Popper perovskites having outstanding optical properties. Here, the coherent spin dynamics in Ruddlesden–Popper (PEA)2PbI4 perovskites is investigated by picosecond pump–probe Kerr rotation in an external magnetic field. The Larmor spin precession of resident electrons with a spin dephasing time of 190 ps is identified. The longitudinal spin relaxation time in weak magnetic fields measured by the spin inertia method is as long as 25 μs. A significant anisotropy of the electron g-factor with the in-plane value of +2.45 and out-of-plane value of +2.05 is found. The exciton out-of-plane g-factor of +1.6 is measured by magneto-reflectivity. This work contributes to the understanding of the spin-dependent properties of two-dimensional perovskites and their spin dynamics.
