继Y-Ba-Cu-O之后,具有更高T_5的Bi-Sr-Ca-Cu-O(简称BSCCO)体系的发现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。由于在制备BSCCO过程中存在复杂的Ca、Sr和Cu复合氧化物,要得到稳定的110K相相当困
Following the Y-Ba-Cu-O, the discovery of Bi-Sr-Ca-Cu-O (BSCCO) systems with higher T_5 has attracted much interest in HTS research. Studies have shown that there are 110K and 80K2 superconducting phases in BSCCO. Due to the presence of complex Ca, Sr and Cu complex oxides in the preparation of BSCCO, it is quite difficult to obtain a stable 110K phase
