Abstract

A comparison of photoinduced absorption spectra in AMnO 3 with A = La 3+, Nd 3+, Ca 2+ is presented. The spectra are analyzed in the framework of photon assisted polaron hopping. In contrast to LaMnO 3 and NdMnO 3 the photoinduced absorption spectrum of CaMnO 3 shows distinct contributions from photoexcited holes and electrons. Both contributions are identified, and our results imply that magnitude of electron-phonon coupling constant for electrons in Mn eg orbitals in CaMnO 3 is significantly smaller than in LaMnO 3.
