Oxygen-Ionic Conductivity in Isovalent-Doped Layered BaLaInO4-Based Perovskites

The oxygen-ionic conductivity of isovalent-doped complex oxides characterized by the Ruddlesden-Popper structure is studied. The BaLa0.9Nd0.1InO4 sample was obtained for the first time by substitution in the La sublattice, and its transport properties are studied. A comparing of the results with the data for samples obtained earlier by isovalent substitution in the In-sublattice of BaLaInO4 is presented. The introducing of a dopant is shown to lead to increase in the contribution from oxygen-ionic conductivity and also in the total conductivity by similar to 2 orders of magnitude.

Automated summary

The oxygen-ionic conductivity of isovalent-doped complex oxides with the Ruddlesden-Popper structure was investigated. The BaLa0.9Nd0.1InO4 sample was synthesized for the first time through substitution in the La sublattice, and its transport properties were studied. A comparison with previous results obtained by isovalent substitution in the In sublattice of BaLaInO4 was presented. It was found that doping increased the contribution from oxygen-ionic conductivity and the total conductivity by approximately 2 orders of magnitude.
