The large-scale use of (RE)-Ba-Cu-O bulk superconductors, where RE=Y, Gd, Sm, is in part, limited by their mechanical properties. These materials belong to the ceramic family of compounds and so are inherently brittle. Alloying of (RE)-Ba-Cu-O with silver enables a significant improvement in the mechanical properties, without a detrimental effect upon the superconducting properties. However,...

In this work we studied the influence of oxygen doping on the critical fields and temperatures of MgB2 thin films and bulk samples. First, oxygen was intentionally introduced into magnesium diboride (MgB2) films by both ex situ annealing and in situ annealing approaches. Our ex situ annealing technique significantly enhanced the upper critical field (HC2), with the extrapolated critical fields...
