Saturation of the High-Temperature Normal-State Electrical Resistivity of Superconductors

Normal state of the copper oxide high-temperature superconductors.

Normal-state C-axis Resistivity of the High-tc Cuprate Superconductors

It is shown that a strong intraplanar incoherent scattering can effectively block the interplanar coherent tunneling between the weakly coupled planes of the highly anisotropic but clean (intrinsic) materials such as the optimally doped high-Tc layered cuprate superconductors. The calculated normal-state C-axis resistivity ρc(T ) then follows the metal-like temperature dependence of the ab-plan...

Mixed state microwave resistivity of cuprate superconductors

We present a compared experimental investigation of the (a, b) plane vortex-state complex resistivity at 48 GHz in YBa2Cu3O7−δ, SmBa2Cu3O7−δ and Bi2Sr2CaCu2O8+x. In YBa2Cu3O7−δ and SmBa2Cu3O7−δ the field dependence of the response can be consistently described by a combination of flux flow and strong pair breaking due to the presence of lines of nodes in the gap. In Bi2Sr2CaCu2O8+x, by contrast...

Filamentary microstructure and linear temperature dependence of normal state transport in optimized high temperature superconductors.

A filamentary model of "metallic" conduction in layered high temperature superconductive cuprates explains the concurrence of normal state resistivities (Hall mobilities) linear in T (T-2) with optimized superconductivity. The model predicts the lowest temperature T0 for which linearity holds and it also predicts the maximum superconductive transition temperature Tc. The theory abandons the eff...

The Dependence of Resistivity on Temperature for Thin Superconductors

Measurements made on superconducting very thin layers are analysed by modelization using 2D FEM. The electric field distribution is established and can be seen the differences of this distribution during the superconductive transition. The calculation of the temperature variation of the resistivity is made based on measured temperature variation of the resistance, taking into account also the e...
