Levitation force at different temperatures and superconducting properties of nano-structured MgB2 superconductors
(ELSEVIER SCIENCE SA, PO BOX 564, 1001 LAUSANNE, SWITZERLAND, 2010-03-04)The levitation and pinning force properties of nanocrystalline MgB2 superconductors prepared by a mechanical alloying technique with varying milling duration have been investigated. Levitation force measurements under ... -
The Magnetic and Structural Properties of SiC-Doped MgB2 Bulks Prepared by the Standard Ceramic Processing
(SPRINGER, 233 SPRING ST, NEW YORK, NY 10013 USA, 2011-01)According to general formula MgB2-x SiC (x) (x=0,0.05,0.1,0.2), MgB2 and SiC-doped bulk superconductors were prepared by the standard ceramic processing. The mixtures of the corresponding powders were sintered at 750 degrees ... -
Magnetic Characterization of SiC Doped Bulk MgB2 Superconductor
(SPRINGER, 233 SPRING ST, NEW YORK, NY 10013 USA, 2011-01)Flux pinning is a very significant mechanism to improve critical current density in MgB2 for many applications, such as developing the performance of wires and tapes. In this study, we have done a systematic study of SiC ... -
Magnetic Properties of YBCO Single-Crystal Grown on Y2O3 Layer by a Cold Top-Seeding Method
(SPRINGER, 233 SPRING ST, NEW YORK, NY 10013 USA, 2012-02)In this work, single-crystal samples 20 mm in diameter were grown by a cold top-seeding method. In order to study the effect of an Y2O3 buffer layer, a compacted precursor was located in a crucible on a buffer layer of ...
