Relationship between pinning mechanism and excess conductivity analysis of x wt% C4H6O5 (x=0.0, 4.0, and 6.0)-added bulk MgB2
(Springer, 2021)
The influence of x wt% C4H6O5 (malic acid) (x = 0.0, 4.0, and 6.0) addition on excess conductivity in bulk MgB2 superconductors were fabricated by two-step solid-state reaction method. Resistivity measurements were carried ...
Pinning properties of Y211 added cold top-seeded YBCO grown on Y2O3 layer
(IOP Publishing Ltd, 2016)
In this study, samples having different composition were prepared with the cold top seeding-melt-growth (TSMG) process by using Nd123 seed. Y2O3 buffer layer was placed to bottom of the pellets consist of Y123: Y211 powder ...
Radioactivity survey and risk assessment study for drinking water in the Artvin province, Turkey
(Springer International Publishing, 2015)
In this study, 117 spring water samples, collected across the Artvin province, were analyzed for gross alpha and gross beta radioactivity. The values of the activity concentrations of the gross a and gross beta measured ...
Flux Pinning in YBCO Single Crystal Grown on Y2O3 Layer
(Springer, 2014)
In this study, single-crystal Y123 samples were
grown by a cold top-seeding method by using Nd123 seed,
and the effect of Y2O3 buffer layer was investigated. The
upper critical magnetic field and coherence length were ...
The Effect of Y2O3 on AC susceptibility measurements of MPMG YBCO superconductor
(Springer, 2013)
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 ...
Magnetic Properties of YBCO Single-Crystal Grown on Y2O3 Layer by a Cold Top-Seeding Method
(Springer, 2012)
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 ...
The effect of using different y2o3 layers on the activation energy and ırreversibility line of mpmg ybco bulk at 1050 degrees c growth temperature
(Springer, 2018)
In this study, three kinds of YBCO samples which are named Y1, Y2 and Y3 were fabricated by a melt–powder–melt–growth
(MPMG) method. The Y1 sample was placed into a platinum (Pt) crucible without Y2O3, the Y2 sample was ...
The effect of growth temperature on the irreversibility line of MPMG YBCO bulk with Y2O3 layer
(Elsevier SCI LTD, 2017)
In this study, three kinds of YBCO samples which are named Y1040, Y1050 and Y1060 were fabricated by Melt-Powder-Melt-Growth (MPMG) method without a seed crystal. Samples seem to be single crystal. The compacted powders ...
The effect of excess Y2O3 addition on the mechanical properties of melt-processed YBCO superconductor
(Springer, 2010)
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 ...
Fluctuation-induced conductivity analysis of Y2O3-layered YBCO single crystal
(Springer, 2016)
In this work, a cylindrical YBa2Cu3O7-x (Y123) sample having 20 mm diameter and 8 mm height was prepared by the cold-seeding method using an Nd123 seed, and the crystal growth process was performed in an alumina crucible ...
