Abstract

Optical conductivity spectra, σ(ω), of perovskite La _1-xCa _xMnO ₃ (x=0, 0.1, 0.3, 0.5, 0.6, 0.8, and 1.0) samples were measured over the wide photon-energy region between 5 meV and 30 eV at room temperature. Systematic changes in σ(ω) due to the Ca doping were observed. These doping studies resolved the controversies involving the two lowest-lying optical transitions of LaMnO ₃. The first and second transitions were identified as e _g↑ ¹ → e _g↑ ² and O 2p → e _g↑ ², respectively.
