Strong Enhancement of Critical Current Density in MgB2 Bulk and Ni-Sheathed Tapes With Very Small Dy2O3 Additions

Strong Enhancement of Critical Current Density in MgB2 Bulk and Ni-Sheathed Tapes With Very Small Dy2O3 Additions

A series of polycrystalline samples were prepared by in situ reaction of Dy2O3 (0.5-5.0 wt.%) with Mg + B. While the superconducting transition temperature, Tc remained largely unchanged, the intragrain distribution of nano precipitates of DyB4 and MgO led to strong enhancement in critical current d...
