Carbon nanotube-doped Fe-sheathed MgB 2 wires and tapes with different doping levels were fabricated by the in situ powder-in-tube method. The phases, microstructures and flux pinning were characterized by XRD, SEM/TEM, magnetic and transport-property measurements. It is found that carbon nanotubes
