Electronic Transport through YBCO Grain Boundary Interfaces between 4.2 K and 300 K
C. W. Schneider, S. Hembacher, G. Hammerl +5
The current-induced dissipation in YBCO grain boundary tunnel junctions has been measured between 4.2 K and 300 K. It is found that the resistance of 45 degree (100)/(110) junction…
A possible solution of the grain boundary problem for applications of high-Tc superconductors
G. Hammerl, A. Herrnberger, A. Schmehl +4
It is shown that the critical current density of high-Tc wires can be greatly enhanced by using a threefold approach, which consists of grain alignment, doping, and optimization of…
Large grain boundary area superconductors
G. Hammerl, H. Bielefeldt, S. Leitenmeier +4
For many applications of polycrystalline high-Tc superconductors the small critical currents of the grain boundaries pose a severe problem. To solve this problem we derive novel de…
