Mg(B,O)2 precipitation in MgB2
X. Z. Liao, A. Serquis, Y. T. Zhu +5
MgB2 samples prepared by solid-state reaction were investigated using high-resolution transmission electron microscopy (HREM), X-ray energy-dispersive spectroscopy (EDX), electron…
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…
Observation of coherent oxide precipitates in polycrystalline MgB2
R. F. Klie, J. C. Idrobo, N. D. Browning +4
Here we describe the results of an atomic resolution study of oxygen incorporation into bulk MgB2. We find that ~20-100 nm sized precipitates are formed by ordered substitution 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…
