高临界电流密度Y-Ba-Cu-O系超导体的研究

Studies on high J_C superconductor in Y-Ba-Cu-O compound system

研究了长时间流氧烧结、高温微熔-回火处理、高温淬火-回火处理等对Y Ba Cu O系超导体临界电流密度JC的影响,找到了Y Ba Cu O系超导体提高临界电流密度JC的加工工艺,且发现JC与磁通钉札有关———磁通钉札越强,临界电流密度JC越大.

This paper studied the effect to JC by sintering in oxygen or sintering with high temperature or quenching in air in the superconductor of YBaCuO compound system.It found the technology to increase the JC value of the superconductor of YBaCuO compound system,and found that JC is related to magnetic fixation,the higher it is the bigger the JC.
