Zusammenfassung: | Ⅰ. INTRODUCTIONSince the discovery of oxide superconductor YBa2Cu3O7-δ with transition temperature above liquid nitrogen one year ago, a tremendous amount of work has been done on oxide superconductors in thousands of laboratories in the world. It has already been shown that yttrium could be replaced by other rare-earth elements except |
