Abstract
The reflection and absorption spectra and the resistivity data for La0.93Sr0.07MnO3, La0.9Sr0.1MnO3, La0.85Sr0.15MnO3, La0.92Ca0.08MnO3 and La0.85Ba0.15MnO3 single crystals have been collected and analyzed by using small lattice polaron theory. The activation energies of the polaron hop are determined. The lattice polarons are found to be dominated in the electronic transport and optical properties in the paramagnetic state in La0.93Sr0.07MnO3, La0.92Ca0.08MnO3 and La0.85Ba0.15MnO3 crystals. It is shown that lattice polaron involves more than one Mn site.
