Lattice paramenter, lattice disorder and resistivity of carbohydrate doepd MgB2 and their correlation with the transition temperature
J. H. Kim, Sangjun Oh, X. Xu +4
The change in the lattice parameters or the lattice disorder is claimed as a cause of the slight reduction in the transition temperature by carbon doping in MgB2. In this work, an…
Correlation between doping induced disorder and superconducting properties in carbohydrate doped MgB2
J. H. Kim, S. X. Dou, Sangjun Oh +4
A comprehensive study of the effects of carbohydrate doping on the superconductivity of MgB2 has been conducted. In accordance with the dual reaction model, more carbon substitutio…
Thermal strain-induced enhancement of electromagnetic properties in SiC-MgB2 composites
R. Zeng S. X. Dou, L. Lu, W. X. Li +4
Strain engineering has been used to modify materials properties in ferroelectric, superconducting, and ferromagnetic thin films. The advantage of strain engineering is that it can…
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…
