摘要
采用高温淬火方法制备了Tc在27.4K至92.4K之间的一组不同氧含量的PMP(粉末熔融工艺)法YBCO超导体。通过对这些超导体样品的磁滞回线及不可逆线的研究发现,随着氧空位的增加。
A series of PMP-processed YBCO superconductors with different oxygen content and T c between 27.4-92.4K have been prepared by quenching from high temperatures. The studies of magnetic hysteresis and irrversibility line of these samples reveal that the magnetic flux pinning force decreases with the increase of oxygen deficiency.
