Explanation

It is also called high-temperature superconductor. compound superconductor characterized by copper oxide surface. Most of them have derived layered perovskite like structures. They have single-layer or multi-layer two-dimensional Cu () 2 planes, so they are also known as layered oxide superconductors. Generally, they are multi layered oxide structures with copper as the main element; It has typical anisotropic characteristics. The typical cuprate oxides superconductor family is divided into La system, Y system, Bi system, T1 system, Hg system, etc. The charge carriers of these superconductors are holes, which are called "hole type superconductors". For Nd systems, such as neodymium cerium copper oxide system (where Nd can be replaced by some lanthanide elements, whose charge carriers are electrons, called "electronic superconductors"), cuprate oxides superconductor are the most promising superconductors with practical value at present, among which REBCO (RE represents rare earth elements), K2223 and Bi2212 are recognized as practical superconducting materials. Low cost and high performance second generation high temperature superconducting tape (REBCO) is a research hotspot in the field of practical superconducting materials.
