Drastic change of electrical conductivity in Pr2CuO4 by isovalent La doping

Abstract

How to affect the transport properties of complex oxides was considered using the uncommon example of Pr_2−xLa_xCuO₄. It was established that appropriate La doping in Pr₂CuO₄ leads to a noticeable increase in high-temperature electrical conductivity. The reason for such changes are discussed from the viewpoint of possible charge redistribution in Pr_2−xLa_xCuO₄.
