Comparative Investigation on Magnetic Behavior of Partial Rare Earth Element (Re: Lu, Yb, and Dy) Substituted Y0.5Re0.5BCO (123) Superconductors
(Springer, 2020)Partial Re (rare earth elements: Lu, Yb and Dy) substituted YBaCuO (123) superconductors synthesized by solid-state reaction (SSR) procedure have been investigated via x-ray diffraction, scanning electron microscopy, a.c. ... -
Complete flux jumping in nano-structured MgB2 superconductors prepared by mechanical alloying
(ELSEVIER SCIENCE SA, PO BOX 564, 1001 LAUSANNE, SWITZERLAND, 2009-07-08)High density nano-crystalline MgB2 bulk superconductors with induced pinning centres were prepared from elemental precursors by a sequence of ball milling, heat treatment, and final pressing. The XRD results revealed the ... -
The Effect of Dy Doping on the Magnetic Behavior of YBCO Superconductors
(Springer, 2016)The effect of dysprosium (Dy) doping on yttrium barium copper oxide (YBCO) prepared by conventional solid-state reaction method has been investigated by means of XRD, AC susceptibility, and DC magnetization measurements. ... -
Improvement of Current Density of Different Atmosphere-Sintered Y358 Superconductors
(Springer, 2016)Y3Ba5Cu8O18 (Y358) which is the last family member of YBCO superconducting material was produced by a solid-state reaction technique. During the production process, superconducting samples were sintered in different ... -
Irreversibility Line and Flux Relaxation Bi:2223/Ag tape Prepared by CTFF Technique : H // c axis
(SPRINGER, 233 SPRING ST, NEW YORK, NY 10013 USA, 2010-04-29)We have studied flux dynamics in Bi:2223/Ag tape prepared by the CTFF technique in the orientation of H//c axis. Irreversibility line (IL) of a Bi:2223/Ag tape has been determined from AC susceptibility and the DC magnetization ... -
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 ... -
Magnetic Relaxation in a Y0.5Lu0.5Ba2Cu3Oy Superconductor at Various Magnetization Levels
(Springer, 2015)The evolution of the rate of flux creep along the major hysteresis envelopes in a Y(0.5)Lu(0.5)Ba(2)Ca(3)Oy sample synthesized by a modified melt powder melt growth (MPMG) method at 25 K has been investigated. Magnetic ... -
Specification of Some Superconductivity Parameters by Adding Lutetium to the YBCO (358) Ceramic Superconductor
(Springer, 2021)Superconducting specimens of Y3-xLuxBa5Cu8O18+delta (where x = 0, 0.2, 0.4, 0.5) ceramic were fabricated via the solid-state route (SSR). The structural and superconducting features of the specimens were analyzed using ...
