The Effect of Excess Y2O3 Addition on the Mechanical Properties of Melt-Processed YBCO Superconductor
(SPRINGER, 233 SPRING ST, NEW YORK, NY 10013 USA, 2010-12)In this study, two kinds of melt-processed YBCO samples with Y2O3 addition were fabricated and their microstructures were defined by XRD analysis and polarized light optical microscopy. The mechanical properties of these ... -
The Effect of Y2O3 on AC Susceptibility Measurements of MPMG YBCO Superconductor
(SPRINGER, 233 SPRING ST, NEW YORK, NY 10013 USA, 2013-04)In this study, two kinds of melt-powder-melt-growth (MPMG) YBCO sample grown on a buffer layer of Y2O3 addition were fabricated. The compacted powders were located on a crucible with Y2O3 powder freely poured and a buffer ... -
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 ... -
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 ...
