日本名古屋大学早川尚夫教授等的研究小组与日本特殊陶业公司共同研制成临界温度达97K的铋系超导薄膜。 铋系超导体虽在整体上其临界温度(115K)比钇系的(90K)高,但因构成五元系的元素种类多,晶体结构复杂,致使薄膜化时的临界温度下降。早 Japan’s Nagoya University Professor Hayakawa Hayashi and other research groups and Japan’s special pottery co-developed a critical temperature of 97K bismuth superconducting film. Although the bismuth-based superconductor has a higher critical temperature (115K) than the yttrium-based (90K) as a whole, the bismuth-based superconductor has a large number of elements and a complex crystal structure, resulting in a decrease in the critical temperature during the thinning. early
