摘要：
High-density cylindrical MgB2 superconductors were manufactured using an ex situ powder in tube extrusion technique. The superconducting properties of the steel-sheathed MgB2 samples were examined with respect to their magnetisation responses, critical temperature and current density. The critical current density of the superconductor was determined by means of magnetisation measurements using Bean’s critical state model. Jc reached a maximum of 4×105 A/cm2 at 5 K.
