Sr3Cu5O8+x和CaSrCu5O5+x的结构和电学性质
摘要:
继Y-Ba-Cu-O之后,具有更高T5的Bi-Sr-Ca-Cu-O(简称BSCCO)体系的发现[1,2]引起了人们对高温超导研究的兴趣。研究表明,在BSCCO中存在110K和80K2个超导相[3,4]。

THE STRUCTRUE AND ELECTRIC PROPERTY OF Sr3Cu5O8+x AND CaSrCu3O5+x
Abstract:
The compounds with the compositions of Sr3Cu5O8+x and CaSrCu3O5+x have been syn-thesized by solid phase reaction method. The crystal structures of both compounds are or-thorhombic with a=3.950Å, b=11.479Å and c=13.420Å for Sr3Cu5O8+x and a=6.489Å,b=11.280Å and c=12.240Å for CaSrCu3O5+x, respectively. The oxygen content and oxida-ation state of copper ion were analysized by the iodometric titration. The electric property measurement indicates that both compounds are p-type semiconductor and have lower resis-tivity. They decomposes at around 936℃.
