Improvement of Critical Current Density and Upper Critical Field in MgB2 using Carbohydrate
J. H. Kim, M. S. A. Hossain, X. Xu +6
We evaluated the doping effects of carbohydrate (malic acid, C4H6O5), from 0wt% to 30wt% of total MgB2, on the phase, lattice parameters, critical temperature, resistivity, and upp…
Enhancement of in-field Jc in MgB2/Fe wire using single and multi-walled nanotubes
J. H. Kim, W. K. Yeoh, M. J. Qin +6
We investigated the doping effects of SWCNTs and MWCNTs on the Tc, lattice parameters, Jc(B), microstructure, and Hc2 of MgB2/Fe wire. These effects systematically showed the follo…
Strong enhancement of critical current density in MgB2 superconductor using carbohydrate doping
J. H. Kim, S. Zhou, M. S. A. Hossain +2
With the relatively high critical temperature (Tc) of 39 K1 and the high critical current density (Jc) of > 100000 A/cm2 in moderate fields, magnesium diboride (MgB2) superconducto…
Drastic improvement of surface structure and current-carrying ability in YBa2Cu3O7 films by introducing multilayered structure
Alexey V. Pan, Serhiy Pysarenko, Shi X. Dou
Much smoother surfaces and significantly improved superconducting properties of relatively thick YBa2Cu3O7 (YBCO) films have been achieved by introducing a multilayered structure w…
The doping effect of multiwall carbon nanotube on MgB2/Fe superconductor wire
J. H. Kim, W. K. Yeoh, M. J. Qin +2
We evaluated the doping effect of two types of multiwall carbon nanotube (CNT) with different aspect ratios on MgB2/Fe monofilament wires. Relationships between microstructure, mag…
Alignment of Carbon Nanotube Additives for Improved Performance of Magnesium Diboride Superconductors
Shi Xue Dou, Waikong Yeoh, Olga Shcherbakova +8
The rapid progress on MgB2 superconductor since its discovery[1] has made this material a strong competitor to low and high temperature superconductors (HTS) for applications with…
