| 摘 要： | 采用PMP工艺在空气中成功制备了Ф17mm的单畴Gd-Ba-Cu-O超导体。利用Gd2O3代替Gd211的添加，同样可以提高Gd-Ba-Cu-O的超导性能，并且可以降低样品的制备成本。但过量的Gd2O3的添加会造成Gd-Ba-Cu-O超导体中Gd-Ba固溶体的增加，从而降低样品的超导性能。本实验中Gd2O3的最佳添加量为0．15mol，制备的样品捕获磁通达到0．36T(77K)。

| Abstract: | Single domain bulk Gd-Ba-Cu-O superconductors 17 mm in diameter have been successfully grown by powder-melt-processing (PMP) in air. The superconducting properties of Gd-Ba-Cu-O may be improved by substituting Gd2O3 for Gd211 addition and the cost of preparation can be decreased. However a solid solution of Gd-Ba forms in response to the inclusion of excess Gd2O3, and the superconducting properties of the bulk Gd-Ba-Cu-O decrease. The addition of 0.15 mol percent of Gd2O3 is found to be optimal and leads to a trapped field of 0.36 T at 77 K. |
