Magnetic field processing to enhance critical current densities of MgB2 superconductors
S. X. Dou, W. K. Yeoh, O. Shcherbakova +5
Magnetic field of up to 12 T was applied during the sintering process of pure MgB2 and carbon nanotube (CNT) doped MgB2 wires. We have demonstrated that magnetic field processing r…
Large Upper Critical Field and Irreversibility Field in MgB2 wires with SiC additions
M. D. Sumption, M. Bhatia, E. W. Collings +4
Resistive transition measurements are reported for Magnesium diboride strands with SiC dopants. The SiC was added as 10 mol of SiC to 90 mol of binary magnesium diboride. Three dif…
Irreversibility Field and Flux Pinning in MgB2 with and Without SiC Additions
M. D. Sumption, M. Bhatia, E. W. Collings +4
Critical current density was measured at 4.2 K for MgB2 strands with and without SiC additions. In some cases measurements were performed on longer (1 m) samples wound on barrels,…
Effect of Nano Scale Fe Doping on Superconducting Properties of MgB2
S. X. Dou, S. Soltanian, Y. Zhao +3
Iron is an important sheath material for fabrication of MgB2 wires. However, the effect of Fe doping on the superconducting properties of MgB2 remains controversial. In this work,…
Effect of carbon nanotube doping on critical current density of MgB2 superconductor
S. X. Dou, W. K. Yeoh, J. Horvat +1
The effect of doping MgB2 with carbon nanotubes on transition temperature, lattice parameters, critical current density and flux pinning was studied for MgB2-xCx with x = 0, 0.05,…
Improvement of critical current in MgB2/Fe wires by a ferromagnetic sheath
J. Horvat, X. L. Wang, S. Soltanian +1
Transport critical current (Ic) was measured for Fe-sheathed MgB2 round wires. A critical current density of 5.3 x 10^4 A/cm^2 was obtained at 32K. Strong magnetic shielding by the…
