Abstract

A plane-chain model of superconductivity is proposed for the high temperature superconductor YBa₂Cu₃O_7-x. The pair condensation which is assumed to occur in both the 2D CuO₂ planar sheets and the 1D CuO chains is assumed to be due to the exchanges of the spin fluctuations in sheets and in chains. The carriers in the sheets are coupled to those in the chains by two particle (pair) tunneling. The effect of this coupling on the T_c are examined by looking at the one loop corrections to the Eliashberg equations. The resulting strong coupling expressions for the T_c are very similar to the one previously obtained in a Ginzburg-Landau analysis of the model.
