Transport critical current density in Fe-sheathed nano-SiC doped MgB2 wires

open access: yes, 2002
The nano-SiC doped MgB2/Fe wires were fabricated using a powder-in-tube method and an in-situ reaction process. The depression of Tc with increasing SiC doping level remained rather small due to the counterbalanced effect of Si and C co-doping.
