Abstract

Magnetoabsorption spectra of (CH₃NH₃)PbI₃ are investigated in the Faraday configuration up to 40 T at 4.2 K. The compound consists of three-dimensional networks of corner-sharing octahedra [PbI₆]^4-. The Zeeman splitting and the diamagnetic shift are observed, and the effective g-factor and the diamagnetic coefficient are 1.2 ± 0.1 and (2.7 ± 0.1) × 10^-6 eV/T², respectively. From the diamagnetic shift, the Bohr radius, the binding energy and the reduced mass of the exciton are estimated to be 28 Å, 37 meV and 0.12m₀, respectively. The exciton in (CH₃NH₃)PbI₃ is one of typical Wannier-type excitons with large radius, which is in contrast with the exciton in (C₁₀H₂₁NH₃)₂PbI₄, consisting of two-dimensional networks of [PbI₆]^4-.
