Dependence of magnetoelectric properties on sintering temperature for nano-SiC-doped MgB2/Fe wires made by combined in situ/ex situ process

Very fine nano-SiC particles (<15 nm) were doped into a MgB2 superconductor. The influence

of self-field supercurrent on the high-field performance of the nano-SiC-doped MgB2/Fe wires

is discussed based on comparison of the critical current densities of the in situ processed nano-SiCdoped MgB2 wires and those of the nano-SiC-doped MgB2/Fe wires processed by the combination of in situ/ex situ methods.
