The effect of excess Y2O3 addition on the mechanical properties of melt-processed YBCO superconductor

Aydıner, Alev; Başoğlu, Mehmet; Yanmaz, Ekrem; Çakır, Bakiye (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 ...
The Effect of Y2O3 on AC susceptibility measurements of MPMG YBCO superconductor

Çakır, Bakiye; Aydıner, Alev; Başoğlu, Mehmet; Yanmaz, Ekrem (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

Aydıner, Alev; Çakır, Bakiye; Başoğlu, Mehmet; Seki, Hironori; Wongsatanawarid, Atikorn; Murakami, Masato; Yanmaz, Ekrem (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 ...
