High-Temperature Superconductivity

چکیده
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 layers, which is why they have almost the same ∼49 K onset temperatures for superconductivity.

INVESTIGATION OF SUPERCONDUCTIVITY AND MAGNETIC PROPERTIES OF BI2SR2CA2CU3O10+Θ CERAMIC SUPERCONDUCTOR WITH ADDITION OF SILICON CARBIDE NANOPARTICLES
In this research, the effect of addition of silicon carbide (SiC) nanoparticles on the improvement of the structural, superconductivity, magnetic, and flux pinning properties of high-temperature superconductor Bi1.6Pb0.4Sr2Ca2Cu3O10+θ (Bi-2223) was investigated. The Bi-2223 ceramic superconductor was prepared using the sol-gel method, and silicon carbide nanoparticles were modified by Azobisiso...

The superconductivity was discovered in 1911. In the same year, Sumitomo Electric Wire & Cable Works was established (Foundation was in 1897 as Sumitomo Copper Rolling Works), and laid the first Japan-made high-voltage underground cables. In 2011, we will celebrate the centennial anniversary of the discovery of superconductivity, and a high-temperature superconducting (HTS) power cable will be ...
متن کاملDesign for a Room-Temperature Superconductor
The vision of “room-temperature superconductivity” has appeared intermittently but prominently in the literature since 1964, when W. A. Little and V. L. Ginzburg began working on the problem of high-temperature superconductivity around the same time. Since that time the prospects for room-temperature superconductivity have varied from gloom (around 1980) to glee (the years immediately after the...
متن کاملRecent Advances in High-Temperature Superconductivity
After more than 15 years of intense research since the discovery of high-temperature superconductivity [1], many interesting physical phenomena unique to the cuprate superconductors are better understood, and various applications have been realized. However, the underlying mechanism for high-temperature superconductivity remains elusive, largely due to the complication of numerous competing ord...
متن کاملHigh-Temperature Superconductivity: History and Outlook
HISTORY OF HIGHTEMPERATURE SUPERCONDUCTIVITY After superconductivity was discovered by Onnes in 1911, many superconductors were discovered and the critical temperature rose year by year. More than 2000 superconducting materials had been discovered by 1975, and the critical temperature had reached 22.3 K with the discovery of Nb3Ge in 1973. After that, however, no higher critical temperature was...
