All-high Tc Josephson tunnel junction: Ba1 - xKxBiO3/Ba1 - xKxBiO3 junctions
Abstract
We have fabricated all-high Tc superconducting tunnel junctions in the material Ba1-xKxBiO3. The junctions are of very high quality and have a Josephson supercurrent. For the low-resistance junctions, the IcR product approaches the theoretical limit.
