BPSCCO Süperiletken Malzemeler Üzerine Seryum Ekleme ve Titanyum Katkılamasının Etkisi

Bu çalışmada yüksek miktarda saf Bi-2212 fazını elde etmek için örnekler 2234 faz kompozisyonundan hazırlandı. Geleneksel katı hal tepkime yöntemi ile x = 0,05 and y = 0; 0,05; 0,1; 0,2 için (BiPb)2CexSr2Ca3Cu4-yTiyO12+? bileşikleri üretildi. Yapı üzerine Seryum ekleme ve titanyum katkılamanın etkileri elektriksel direnç, XRD desenleri ve manyetik histerezis döngü ölçümleri ile araştırıldı. Bütün örneklerin yeterli süperiletkenlik karakteristiğini içermediği anlamına gelen yarıiletken davranışı sergilediği bulundu. Bütün örneklerin geçiş sıcaklığında bir pik verdiği gözlemlendi. Buna ek olarak düşük sıcaklıklarda histerezis döngü ölçümleri, örneklerde istenilen Bi-2212 fazların oluştuğu anlamına gelen II. Tip süperiletkenlerin temel meissner etkisine sahip olduğunu göstermektedir. Histerezis döngülerinin genişliğinde azalma Ti konsantrasyonu ve artan sıcaklık ile artmaktadır.

Effect of Cerium adding and Titanium doping on the BPSCCO Superconductor Materials

In this study the samples were prepared by 2234 phase composition to achieve the high levels of pure Bi-2212 phase. It have been produced the (BiPb)2CexSr2Ca3Cu4-yTiyO12+? compounds for x = 0.05 ve y = 0, 0.05, 0.1, 0.2 by conventional solid state reaction method. The effects of cerium adding and Ti doping on the structure have been investigated by electrical resistance, XRD patterns and magnetic hysteresis loop measurements. XRD results clearly show that all samples It has been found that all samples show semiconducting behavior, which means not to include adequate superconducting characteristics. It has been observed all the samples give a peak at transition temperatures. In addition, the hysteresis loop measurements at low temperatures show that samples have the basic meissner effect of type II superconductors, meaning that the desired Bi-2212 phases in samples occur. The decrease at the magnitude of hysteresis loops increase with increasing temperature and Ti concentration.
