摘要

Superconducting properties and fishtail effect of powder melting processed Y-Gd-Ba-Cu-O have been investigated through X-ray diffraction pattern, a. c. susceptibilty and SQUID magnetometer. It is found that the fishtail effect can be observed in Gd-doped YBCO (T < 70K, H⊥c) while no fishtail appears in the pure YBCO sample. Jc and flux pinning are improved by the partial substitution of Gd for Y. It is expected that the reduction of the Y2BaCuO5 size, stress field pinning and magnetic pinning are responsible for the enhancement of Jc.
