Superconducting properties of Al-stabilized MgB2 wires

Journal Article


Abstract


  • FeMgB2 wires have been prepared using an in situ technique and the standard PIT method. Short samples of FeMgB2 wire were sintered at 750 ðC for 30 min and then coated with Al by a hot aluminizing technique. Transport critical current was measured by the pulsed method with voltage contacts attached directly onto the Al surface. The transport Jc of AlFeMgB2 wires reached 3 à104 A/cm2 at 10 K and 5 T and 104 A/cm2 at 20 K and 5 T. The influence of the Al stabilizer on thermomagnetic instabilities and superconducting properties in the FeMgB2 wires is investigated.
