The Effect of Y2O3 on AC Susceptibility Measurements of MPMG YBCO Superconductor
Çakır, Bakiye; Aydıner, Alev; Başoğlu, Mehmet; Yanmaz, Ekrem (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 ... -
Fabrication and properties of dense ex situ magnesium diboride bulk material synthesized using spark plasma sintering
Dancer, C.E.J.; Prabhakaran, D.; Başoğlu, Mehmet; Yanmaz, Ekrem; Yan, H.; Reece, M.; Todd, R.I. (IOP PUBLISHING LTD, DIRAC HOUSE, TEMPLE BACK, BRISTOL BS1 6BE, ENGLAND, 2009-09)High density ex situ magnesium diboride bulks were synthesized from commercial MgB(2) powder using spark plasma sintering under a range of applied uniaxial pressures between 16 and 80 MPa. The microstructure was characterized ... -
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, A.; Murakami, M.; Yanmaz, Ekrem (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 ... -
Synthesis and spectral and thermal characterization of new metal-free and metallophthalocyanines: investigation of their photophysical, photochemical, and thin film properties
Novel tetrasubstituted metal-free (2), zinc (II) (3), cobalt (II) (4), and copper (II) (5) phthalocyanines bearing 2-phenylethanolate groups on the peripheral positions were synthesized by the cyclotetramerization reaction ...
