چکیده
Aspects of the normal state phase of copper oxide planes in high Tc superconductors. Abstract We examine various aspects of the normal state phase of CuO 2 planes in the high Tc superconductors. In particular, within the context of the three band Hubbard model, we study as a function of doping the competition between a charge density wave phase induced by oxygen breathing modes, antiferromagnetic order and paramagnetism. To account for the strong electronic interactions, we use the finite U slave boson method of Kotliar and Ruckenstein.

A high temperature electrochemical oxidation process has been used to produce large single crystals of La 2 CuO 4+δ suitable for neutron scattering experiments. Below room temperature the oxygen-rich phases have structural superlattice scattering peaks which indicate new period-icities ranging from 2 to 6.6 layers perpendicular to the copper oxide planes. A model structure originally proposed f...

Various concentrations of copper were embedded into silica matrix to xerogel forms using copper source Cu(NO3)2∙3H2O. The xerogel samples were prepared by hydrolysis and condensation of Tetraethyl Ortho-Silicate (TEOS) with determination of new molar ratio of the components by the sol-gel method. After ambient drying, the xerogel samples were heated from 60 to 1000˚C at a slow heating rate (50°...
