Abstract

In the current study, different amounts of nano-sized Eu (80 nm) (x = 0.0, 0.20 and 0.25) were substituted to strontium sites in the Bi_1.7Pb_0.3Sr₂Ca₂Cu_2.75Na_0.25O_y system. Ceramic samples produced by the solid state reaction method were analyzed by performing X-ray diffraction measurements (XRD), scanning electron microscope measurements (SEM) and M-H measurements. In the results of X-ray diffraction measurement, it was determined that the main phase structure was Bi-2223 superconductivity phase, although some impurity phases were formed in all samples. In the findings obtained from scanning electron microscopy measurements, it was observed that all samples consisted of flaky plate-like grain structures containing the presence of Bi-2223 phase structure. With the formation of minor impurity phases in the morphological structure, differences in grain behavior have occurred in some regions. M-H measurements were performed to characterize the magnetic properties of the samples. In M-H measurements, diamagnetic behavior, which is characteristic of the Bi-2223 superconductor phase, was observed in sample, nano sized Eu-free.
