Abstract

The MgB2 formation was analyzed physically and chemically and the MgB2/Fe wires were fabricated by powder in tube (PIT) technology. The microstructure of MgB2 in wires was studied by the scanning electrical microscope (SEM), which shows a good connection of grains and the size of MgB2 grain is 1–3 μm. The results ofJ c measured by the standard four probes method show thatJ c value reaches 6.1×104 A/cm2 at 20 K in self field.
