Interface high-temperature superconductivity
Cuprate high-temperature superconductors consist of two quasi-two-dimensional (2D) substructures: CuO2 superconducting layers and charge reservoir layers. The superconductivity is realized by charge transfer from the charge reservoir layers into the superconducting layers without chemical dopants and defects being introduced into the latter, similar to modulationdoping in the semiconductor supe...
متن کاملHigh-Temperature Superconductivity
The widely held notion that high-temperature superconductivity originates in the cuprate-planes is proven to be faulty. In the cuprates such as YBa2Cu3O7, we argue that the superconductivity resides in the BaO layers. This superconductivity is s-wave, not d-wave, in the bulk. The trio of ruthenate compounds, doped Sr2YRuO6, GdSr2Cu2RuO8, and Gd2−zCezSr2Cu2RuO10 all superconduct in their SrO lay...
متن کاملHigh-temperature Anyon Superconductivity
The screening of an applied magnetic field in a charged anyon fluid at finite density (μ 6= 0) and temperature (T 6= 0) is investigated. For densities typical of high-temperature superconducting materials we find that the anyon fluid exhibits a superconducting behavior at any temperature. The total Meissner screening is characterized by two penetration lengths corresponding to two short-range e...
متن کاملAspects of high temperature superconductivity
2014 We present some remarks on special features that distinguish the phenomenology of the new high Tc oxides from that of the conventional superconductors. They include a measurable width of the critical region and a high sensitivity to crystallographic defects. A consistent Landau Ginsburg interpretation it possible, with a short coherence length 03BEab ~ 15 Å and a penetration depth 03BBL ~ ...
متن کاملDilute Annealed Magnetism and High Temperature Superconductivity
It has become increasingly appreciated that the strong antiferromagnetic coupling between in-plane Cu atoms in most of the high-temperature superconductors is not merely fortuitous [ 1-4 ]. However a coherent understanding of exactly how the magnetic interactions influence the observed superconductivity has been elusive. Here we focus on the prototype compound, La2_xSrxCuO 4 ( " 2 1 4 " ) . We ...
