Superconducting nanostructured magnesium diboride

, 2005
Like conventional superconductors, MgB2 is a phonon-mediated superconductor with a relatively long coherence length. Its properties make the prospects for fabricating reproducible uniform Josephson junctions, the fundamental element of superconducting circuits, much more favorable for MgB2 than for high-temperature superconductors. Here, we report bulk
