Özet

In this study, samples with nominal composition of Bi2Sr2Ca1Cu2-x Yb (x) O (y) , where x=0.0, 0.05, 0.1 and 0.25, have been textured using the Laser Floating Zone technique. The effects of different Yb doping on the structure have been investigated by electrical resistivity, scanning electron microscopy, XRD, mechanical and dc-magnetization techniques. It has been found that with increasing Yb3+ doping for Cu, the physical and superconducting properties of structure gradually decrease. J (C) values, calculated using the Bean's model, significantly change, although T (C) is approximately the same for all samples.
