متن کاملsuperconductivity ∗
We present a 2+1-dimensional lattice model for the copper oxide superconductors and their parent compounds, in which both the charge and spin degrees of freedom are treated dynamically. The spin-charge coupling parameter is associated to the doping fraction in the cuprates. The model is able to account for the various phases of the cuprates and their properties, not only at low and intermediate...
متن کاملSuperconductivity, localization and crystallographic phase transition in La(2-x)SrXCuO(4-y)
We report a resistive investigation of superconductivity in the system La2 xSrxCuO4 y on samples which have been analysed by thermogravimetric techniques for oxygen deficiency determination. A maximum superconductive transition temperature is observed in La2 xSrxCuO4 y near the tetragonal-orthorhombic phase transition, together with a resurgence of high temperature superconductivity in non-subs...
متن کاملSuperconductivity and Electric Fields: a Relativistic Extension of Bcs Superconductivity
The effects of static electric fields on the superconducting state are studied within a relativistic extension of the BCS theory of superconductivity.
متن کاملLocalization and Study of Histochemical Effects
A high capacity for accumulation of Mn was reported for sunflower plants. Localization of excess Mn is therefore of special interest for understanding metal tolerance mechanisms in this species. In this study, structural and histochemical alterations caused by Mn accumulation in leaves were investigated in sunflower (Helianthus annuus L. cv. Azar-ghol) plants grown in nutrient solution. In the ...
