Abstract—The effect of isovalent doping Sc3+ → In3+ on the transport properties is studied for complex oxide BaLaInO4 characterized by the Ruddlesden–Popper structure. It is shown that the introduction of scandium increases the oxygen-ionic and protonic conductivity. In the humid air atmosphere at 500°С, both BaLaInO4 and BaLaIn0.9Sc0.1O4 are the protonic conductors with ~90–95% contribution of proton transfer.
