摘要: 简要介绍了利用高温高压合成发现的超导系列CuBa2Can-1CunO2n+2+，即Cu-12n（三元数法）或Cu-12(n-1)n（四元数法），简称Cu-系。比较了Cu-系和其它主要高温超导体的结构和主要性质，指出了Cu-系和YBa2Cu3O6的同构关系，以及Cu-系具有的良好的高温高场特性。Cu-系超导体因仅含碱土和铜的氧化物，化学组成简单、经济、安全，具有潜在的应用开发前景。Abstract: The novel superconducting homologous series CuBa2Can-1CunO2n+2+ (i. e., Cu-12(n-1)n) have been introduced. The compounds can be synthesized only under high pressure high temperature so far. The physical properties of Cu-12(n-1)n are briefly compared with other high Tc superconductors, while the advantages of the Cu-12(n-1)n superconductors in terms of simple composition, higher Tc and better high temperature high magnetic field properties are stressed.
