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…
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…
On the sample size dependence of the critical current density in MgB superconductors
M. J. Qin, S. Keshavarzi, S. Soltanian +3
Sample size dependent critical current density has been observed in magnesium diboride superconductors. At high fields, larger samples provide higher critical current densities, wh…
Evidence for Transition Temperature Fluctuation Induced Pinning im MgB Superconductor
M. J. Qin, X. L. Wang, H. K. Liu +1
The magnetic field dependent critical current density of a MgB bulk sample has been obtained by means of magnetization hysteresis measurements. The curves at…
