Abstract

The electronic states of Cu in crystals were investigated in the framework of the Slater model of neutral atoms in crystals. It was shown that the closeness of divalent 3d94s2 and monovalent 3d104s states of Cu and the strong dependence of their mutual arrangement on the crystal field strength is the distinctive feature of Cu among transition metal elements and other neighbors in Periodic Table. These Cu states show the tendency to cross in Cu-O planes of cuprate superconductors, when superconducting composition is approached. © 1996 The American Physical Society.
