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…
Coated conductors containing grains with big aspect ratios
S. Leitenmeier, H. Bielefeldt, G. Hammerl +3
It is shown that the critical currents of high-Tc superconducting tapes fabricated by the coated conductor technologies are enhanced considerably if grain arrangements with large e…
