The role of chain superconductivity in the "123" HTSC: A microscopic approach

A plane-chain model of superconductivity is proposed for the high temperature superconductor YBa2Cu3O7-x. The pair condensation which is assumed to occur in both the 2D CuO2planar sheets and the 1D CuO chains is assumed to be due to the exchanges of the spin fluctuations in sheets and in chains. The...
