摘要

块状高温超导体(HTS)在其非织构形式下由晶界处的弱链接网络组成。薄弱环节是由于不正确的化学计量比或排列不当的晶粒面，并大大降低了临界电流密度。高温块状超导体Y1 Ba2 Cu3 O7-δ (YBCO)以以下重量百分比掺杂氧化石墨烯:0,0.5和0.7 wt. %。在零场冷却(ZFC)和场冷却(FC)条件下进行电阻与温度的测量，以确定临界转变温度(Tc)并研究对弱环节的影响。结果表明，掺杂样品中的Tc增加，弱链效应有所改善。

Effect of Graphene Oxide Doping on Bulk High Temperature Superconductors For Power Applications

Bulk high temperature superconductors (HTS) in their non-textured form consists of a network of weak-links at its grain boundaries. The weak-links are a result of an incorrect stoichiometric ratio or misaligned grain planes, and greatly reduce the critical current density. High temperature bulk superconductor, in our case Y1 Ba2 Cu3 O7-δ (YBCO), was doped with graphene oxide in the following weight percentages: 0, 0.5 and 0.7 wt. %. Resistance vs Temperature measurements were taken in zero field cooling (ZFC) and field cooling (FC) conditions in order to determine critical transition temperature (Tc) and to study the effect on the weak-links. It is observed that Tc in doped samples increased and there is an improvement in the weak-link effect in doped samples.
