Abstract Studies of the effects of doping MgB2 bulk and steel-sheathed wires with V are presented. Samples having the nominal composition Mg1-xVxB2 (x = 0, 0.05, 0.10, 0.15) have been fabricated and investigated to understand the role of V doping on the phase formation, microstructure and superconducting properties. Characterization of superconducting samples was carried out using XRD, SQUID, ESEM/EDS, and Ic measurements. Results show an enhancement of superconducting properties with V doping, and suggest the presence of V in the superconducting phase. Wires with Jc values as high as 1.4 x 105 A/cm2 have been achieved.
