Fabrication and critical current density in 16-filament stainless steel/Fe/MgB2 square wire

摘要

Sixteen-filament stainless steel/Fe/MgB2 wires were fabricated by the powder-in-tube method followed by groove rolling and a short 8 min/950 degreesC heat treatment. The wires were characterized using SEM, and vibrating sample magnetometery. Magnetic critical current densities of 3.4 x 10(5) A/cm(2) at 0.5 T and about 1.9 x 10(5) A/cm(2) at 1 T at 5 K were achieved. (C) 2002 Elsevier Science Ltd. All rights reserved. References: 16
