Fabrication of superconducting MgB2 from boron oxide (B 2O3), and its microstructural and electrical characterization
(National Institute of Optoelectronics, 2005-02)
The discovery of superconducting MgB2 (39 K) draws attention to it as a new material for applications based on superconductivity. Many researchers successfully synthesized MgB2 using commercial boron and magnesium. In this ...
Effect of Al substitution on structural and electrical properties of Bi1.6Pb0.4Sr2CaCu2-x Mx O8+δ superconducting ceramics
In this work we study the effect on structural and electrical properties of superconducting compound Bi1.6Pb0.4Sr 2CaCu2-y My O8+δ were M=Al (with y=0-0.6). The samples were prepared by the solid-state reaction method. The ...
Electrical and microstructural properties of superconducting MgB 2/Mg composites
(Trans Tech Publications, 2004)
MgB2/Mg composites were prepared to improve mechanical properties of brittle superconducting MgB2. MgB2 and Mg powders were mixed at different weight ratios and uniaxially pressed in a cylindrical dye at 0.5 GPa and at ...
Reply to "comment on 'Counterintuitive consequence of heating in strongly-driven intrinsic junctions of Bi 2Sr 2CaCu 2O 8+δ mesas'"
(American Physical Society, 2011-10)
The main criticism raised in the preceding Comment concerns our suggestion that sharp conduction peaks in Bi 2Sr 2CaCu 2O 8+δ mesas, along with absent dip-hump features, may, in general, be a result of self-heating. The ...
Thermally and optically tunable sub-terahertz superconducting fishnet metamaterial
In this paper, a novel fishnet metamaterial structure is designed and analyzed under different material combinations and under different active controlling techniques. The results indicate that, the proposed fishnet ...
MgB2 superconducting thin films grown by magnetron sputtering
(National Institute of Optoelectronics, 2007-02)
In this study, we report the growth and properties of MgB2 thin films on polycrystalline Al2O3 substrates. A composite MgB2 target was produced by MgB2 and Mg powder mixing, using a hot pressing technique. MgB2 thin films ...
