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 C 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 3 104 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.
