Effect of heat treatments on superconducting properties and connectivity in K-doped BaFe2As2
Abstract Fe-based superconductors and in particular K-doped BaFe2As2 (K-Ba122) are materials of interest for possible future high-field applications. However the critical current density (J c ) in polycrystalline Ba122 is still quite low and connectivity issues are suspected to be responsible. In th...
