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…
Very fast formation of superconducting MgB2/Fe wires with high Jc
X. L. Wang, S. Soltanian, J. Horvat +3
In this paper we have investigated the effects of sintering time and temperature on the formation and critical current densities of Fe-clad MgB2 wires. MgB2 wires were fabricated u…
High transport critical current density above 30 K in pure Fe-clad MgB2 tape
S. Soltanian, X. L. Wang, I. Kusevic +5
Fe-clad MgB2 long tapes have been fabricated using a powder-in-tube technique. An Mg + 2B mixture was used as the central conductor core and reacted in-situ to form MgB2. The tapes…
Dependence of the flux creep activation energy on current density and magnetic field for MgB2 superconductor
M. J. Qin, X. L. Wang, H. K. Liu +1
Systematic ac susceptibility measurements have been performed on a MgB bulk sample. We demonstrate that the flux creep activation energy is a nonlinear function of the current…
