Abstract

Band structure calculations for Cu03 and Cu02 chain compounds as well as for zigzag Cu204 double chain compounds are reported. These cuprate chains form the basic elements of a rich and beautiful variety of cuprate structures. From the dispersion of the antibonding band crossing the Fermi energy the exchange interaction is estimated and qualitative trends in the antiferromagnetic ordering at low temperatures are well explained. From the comparison of exact diagonalization studies of corresponding periodic chains with frequently used approximations a restricted validity of the latter with respect to the hole doping amount is found. The possibility of CDW-BOW states is discussed on the basis of self-consistent adiabatic studies. Chain aspects for superconductivity and the possible relationship to the stripe scenario are briefly discussed.

    The crystal structures of compounds containing Ge or Si are characterized by the presence of a second structural element: the GeO4 or SiO4 tetrahedron, respectively. For this reason in the chemical literature the classification notation as germanates or silicates, respectively, is used. However, the band structure calculations for GeCuO3 and SiCuO3[23, 1] show clearly that the states near the Fermi energy which determine the electronic and magnetic properties are predominant of Cu and O character. The corresponding compounds are therefore strongly correlated charge transfer insulators in the sense of the classification of Sawatzky, Zaanen, and Allen. The Cue+ ions are in a strongly elongated oxygen octahedral environment and hence again dominated by the COP states. For our purposes one could therefore write for instance (GeO)CuO2 to emphasize the edge-shared COPs network instead of the standard CuGeO3 notation. Strictly speaking, these compounds should be correctly denoted as germanyl (silicyl) cuprates.Google Scholar
