Abstract

A superconducting Josephson junction element including a first, a-axis oriented, superconductive metal oxide crystal grain having a first area of a {001} plane, and a second, c-axis oriented, superconductive metal oxide crystal grain having a second area of a {110} plane, wherein the first and second crystal grains are in contact with each other at the first and second areas to form a grain boundary therebetween.
