Complete flux jumping in nano-structured MgB2 superconductors prepared by mechanical alloying
High density nano-crystalline MgB2 bulk superconductors with induced pinning centres were prepared from elemental precursors by a sequence of ball milling, heat treatment, and final pressing. The XRD results revealed the main phase was MgB2 with a minor component of MgO. The magnetic moment versus t...
