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…
Microwave performance of high-density bulk MgB2
A. T. Findikoglu, A. Serquis, L. Civale +6
We have performed microwave measurements on superconducting hot-isostatically- pressed (HIPed) bulk MgB2 using a parallel-plate resonator technique. The high density and strength o…
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…
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…
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…
