Abstract

Recently, the electron-doped superconductor Nd-Ce-Cu-O system was discovered but its electronic state has not been clarified yet from first principles. In this paper we report the results of first principles cluster calculations of the electronic states of the Nd2CuO4 and of its cerium-doped system, with the aim of clarifying the features of the electron states in the Nd-Ce-Cu-O systems. For this purpose we adopt a Cu2O7 cluster as an object of study. Since electron correlation is especially important in high temperature copper oxide superconductors we adopt the multi-configuration self-consistent field method with configuration interaction.
