Formation of MgB2 by reactions of Mg with B6Si and Mg with B were compared, the former also producing Mg2Si as a major product. Compared to the binary system, the ternary reactions for identical time and temperature were more complete at 750??C and below, as indicated by higher diamagnetic shielding and larger x-ray diffraction peak intensities relative to those of Mg. MgB2 could be produced at temperatures as low as 450??C by the ternary reaction. Analyses by electron microscopy, x-ray…

Improved critical current properties observed in MgB2 bulks synthesized by low-temperature solid-state reaction
MgB2 bulks were synthesized by the solid-state reaction of Mg and B at 600??C and their superconducting properties were compared with samples heated at 850??C. The samples heated at 600??C exhibited
Significant improvement of activation energy in MgB2∕Mg2Si multilayer films
We obtained a MgB2∕Mg2Si multilayer structure by sequentially switching a stoichiometric MgB2 target and a Si target during off-axis pulsed-laser deposition. The transmission-electron-microscopic
Si addition in in situ annealed MgB2 thin films by pulsed laser deposition
Various amounts of Si up to a level of 18 wt% were added into MgB2 thin films fabricated by pulsed laser deposition (PLD). Si was introduced into the PLD MgB2 films by sequential ablation of a

We report the synthesis and characterization of silicon doped MgB2 films fabricated by hybrid physical?chemical vapor deposition using silane as the doping source. Various amounts of Si up to 9% were
Transport properties of multilayered MgB2/Mg2Si superconducting thin film
Electronic transport measurements have been carried out on superconducting MgB2∕Mg2Si multilayer film, using a standard four-probe method in perpendicular and parallel applied fields. The film, which

TOPICAL REVIEW: Costs of high-field superconducting strands for particle accelerator magnets
The costs of superconducting magnet strands are compared by calculating a 'production scaling factor' P that relates purchase data to the cost of raw materials. Using a consistent method, we
