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...
متن کاملResistivity at low temperatures in electron-doped cuprate superconductors
We measured the magnetoresistance as a function of temperature down to 20 mK and magnetic field for a set of underdoped Pr1.88Ce0.12CuO4− thin films with controlled oxygen content. This allows us to access the edge of the superconducting dome on the underdoped side. The sheet resistance increases with increasing oxygen content whereas the superconducting transition temperature is steadily decre...
متن کاملMottness collapse and T-linear resistivity in cuprate superconductors.
Central to the normal state of cuprate high-temperature superconductors is the collapse of the pseudo-gap, briefly reviewed here, at a critical point and the subsequent onset of the strange metal characterized by a resistivity that scales linearly with temperature. A possible clue to the resolution of this problem is the inter-relation between two facts: (i) a robust theory of T-linear resistiv...
متن کاملNormal-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...
متن کاملAnomalous microwave conductivity due to collective transport in the pseudogap state of cuprate superconductors
The microwave surface impedance Zs5Rs1iXs of HgBa2Ca2Cu3O81d , HgBa2CuO41d , Tl2Ba2CuO61d , and underdoped YBa2Cu3O6.5 is found to be anomalous in that Rs(T.Tc)ÞXs(T.Tc) in the pseudogap state. This implies plasmonlike response and negative permittivities «8(v),0 at microwave frequencies indicating non-Fermi-liquid transport in the ab plane. The anomalous microwave response is shown to arise fr...
