Synthesis of HgSr_2-xY_xCa₂Cu₃O_{8+ δ} Superconducting Compound

Abstract:

The superconductivity phenomenon and the method of preparing the superconductingmercury-based (HgSr2-xYxCa2Cu3O8+δ with x=0 to 0.15) compound were presented in this paper. The physical properties of the compound are presented at a high temperature, with a special focus on the effect of partial substitution of strontium with Yttrium (Y). The effect on structural and electrical properties were investigated. All the samples in the present investigation were subjected to gross structural characterization by X-ray diffraction. The XRD data collected from various have the Hg1223 phase and the analysis showed that all samples correspond to the tetragonal structure. The electrical resistance uses the four probe technology to find the critical temperature and found that it drops from 116 K to 81K by increase the yttrium concentration.
