Abstract
La1−x Lix FeO3 solid solution prepared by solid-phase synthesis in an air environment at atmospheric pressure is found to exist only for x≲0.1. All single-phase samples are p-type semiconductors. An increase in lithium concentration brings about a decrease in their electrical resistivity and thermopower. The results are discussed in terms of the small polaron (SP) model. The SP concentration and mobility are calculated from data on the electrical resistivity and thermopower in the presence of an antiferromagnetic-paramagnetic phase transition. It is shown that the decrease in electrical resistivity of the samples is connected with the increase in both the concentration and mobility of SPs.
