The influence of structural defects on intra-granular critical currents of bulk MgB2
A. Serquis, X. Z. Liao, L. Civale +4
Bulk MgB2 samples were prepared under different synthesis conditions and analyzed by scanning and transmission electron microscopy. The critical current densities were determined f…
Hot isostatic pressing of powder in tube MgB2 wires
A. Serquis, L. Civale, D. L. Hammon +8
The critical current density (Jc) of hot isostatic pressed (HIPed) MgB2 wires, measured by d.c. transport and magnetization, is compared with that of similar wires annealed at ambi…
Microstructure and high critical current of powder in tube MgB2
A. Serquis, L. Civale, D. L. Hammon +5
We report dc transport and magnetization measurements of Jc in MgB2 wires fabricated by the powder-in-tube method, using commercial MgB2 powder with 5 %at Mg powder added as an add…
The degradation of MgB2 under ambient environment
A. Serquis, Y. T. Zhu, D. E. Peterson +4
The superconductivities of samples prepared by several procedures were found to degrade under ambient environment. The degradation mechanism was studied by measuring the change of…
The influence of microstructures and crystalline defects on the superconductivity of MgB2
A. Serquis, X. Y. Liao, Y. T. Zhu +9
This work studies the influence of microstructures and crystalline defects on the superconductivity of MgB2, with the objective to improve its flux pinning. A MgB2 sample pellet th…
