High-Temperature Superconductors

Science, 1997
Developing new approaches for improving the critical current density ( J c) in bulk high-temperature superconductors is important to the commercialization of these materials in power transmission cables and other applications ([1][1]). I. Chong et al . (Reports,[2 May, p.

High-temperature superconductors

2011
This chapter is dedicated to the study of the superconductor–insulator transition in high temperature superconductors. We saw, in Sect.1.3.3, that metal superconductors were not so interesting from the point of view of critical phenomena. This is because their coherence length at T=0 is of the order of a micron, so the critical region is around 10−14K,

High Temperature Superconductors

2023
In this article, we describe the phenomenology of the superconducting state in condensed matter. We start introducing the main properties and experimental signatures of conventional superconductivity in elemental metals and metallic alloys. Next, we focus on unconventional high temperature superconductivity in copper oxides and on the highly complex ...

High-Temperature Superconductors

Journal of Applied Physics, 1968
Superconductors with the highest known transition temperatures to date occur in β-tungsten phases which are rich in Nb3Al. It has been found possible to raise the temperature of Nb3Al (Tc=18.5°K) to above 20°K by replacing some of the Al with Ge.1 The low values found for the electronic-heat-capacity co-efficient, and the almost temperature-independent

High-Temperature Superconductors

2007
Chapter 8 covers the various properties of high-temperature superconductors. These superconductors show significant anisotropy due to the two-dimensional crystal structure composed of superconducting CuO2 layers and insulating block layers. This makes the states of flux lines extremely complicated.

High-temperature superconductors

1993
Abstract Since, as in other superconductors, the current carriers are bosons, in the case of the p-type materials paired holes, to understand many of their properties we need to consider the behaviour of bosons in a non-crystalline environment.
