Abstract

The current research focuses on the effect of partial substitution of yttrium nanoparticles for barium on the electrical and structural properties of the superconducting compound Bi2Ba2-yYyCa2Cu3O10+, where y = 0, 0.1, 0.2, 0.3, and the samples were prepared using the solid state reaction (SSR) method.  The samples were subjected to heat treatment in normal air for 48 hours at 800°C at a heating rate of 10°C/min. X-ray diffraction studies were performed on four materials with deferent yttrium concentrations. The results of X-ray diffraction showed that all samples had a crystal structure with differences in the lattice constants (a, b and c, )with a clear increase in the dimension c = 36.4969 Ao for the second sample when y = 0.1, there was also an increase in the proportion of the higher phase HTP%, which reached 74.76%, when it was y=0.1and the development of The formation of nano-sized granules was observed by the SEM device for the samples, and the element analysis for each sample was examined through EDS examination, as the results showed the presence of the elements and their various proportions in each sample. The critical temperature was also measured, and the results showed that the highest critical temperature is 138 K when the yttrium concentration is 0.1.
