| 摘 要： | The discovery of superconductivity at 39 K in MgB2has attracted a lot of interest in the world15]. Recently, many results on the magnetic and transport properties of bulks have been reported. And high critical currentdensities (Jc) in polycrystalline MgB2 materials indicate that Jc is not limited by the weak link of grain boundaries as high temperature superconductor (HTS), suggestingthat MgB2 has a good potential for electrical engineering applications2,48]. The fabrication of high qua…

| 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. |
