9521888 Mukhopadyay This project is aimed at exploring a new and innovative method of tailoring the superconductor-metal interface by doping the surface of the superconducting oxide with bromine which was found to modify its chemical interaction with metals. Ag-superconductor composite samples with undoped and halogen-doped superconducting oxides will be prepared and comparison of their physical properties (Jc , Tc , microstructure and how each property changes with thermal and electrical cycling) will be made. This study if successful, will provide a new dopant for superconductors, which will improve the overall oxide-metal composites. %%% Surface treatment of oxide superconductors by bromine will be tested. If successful, it will provide a new method for achieving high quality and of better properties superconductor: metal composites.

9521888 MukHopadyay该项目旨在探索一种新的创新方法，通过在超导氧化物的表面掺杂溴来改变其与金属的化学作用，从而调整超导体与金属的界面。我们将制备未掺杂和掺卤素超导氧化物的银超导体复合材料样品，并对其物理性能(J_c、T_c、微观结构以及每种性能随热循环和电循环的变化)进行比较。这项研究如果成功，将为超导体提供一种新的掺杂剂，从而改善氧化物-金属复合材料的整体性能。将测试用溴对氧化物超导体进行的表面处理。如果成功，它将为获得高质量和更好性能的超导体提供一种新的方法：金属复合材料。
