Description Here, effect of single-walled carbon nano-tube (CNT) doping on transition temperature, lattice parameters, critical current density and flux pinning in MgB2 superconductor was studied. The carbon substitution for B was found to enhance critical current density Jc in magnetic fields but depress critical temperature Tc. The depression of Tc is caused by the carbon substitution for B, which is also confirmed by Rietveld analysis of room temperature XRD patterns of doped samples. We achieved enhancement of critical current density (Jc) and flux pinning by almost an order of magnitude, particularly in higher magnetic fields.
