摘要

The effects of excess BaO additions on the properties of NdBCO superconductors have been investigated. It is found that the onset T_c (T_con) of the NdBCO samples (Nd₁Ba₂Cu₃O_y + x BaO) with differential excess BaO additions (x = 0, 0.2, 0.4, 0.6) are very complicated. It is difficult to conclude that excess BaO addition can depress the substitution degree of Nd atoms on Ba sites and improve the T_con of the NdBCO superconductors by the melt-growth process in air. A new method (Ba-rich melt growth or BaRMG) has been developed for the preparation of small-size (in millimeter order) NdBCO single crystal in small scales. The crystals are suitable to be used as seeds for the preparation of large single-domain YBCO bulk superconductors.
