Preparation and Characterization of Y123 Superconductor using Hall Effect Measurement

Abstract

In this research, group Y123 superconductors were prepared by the solid-state reaction method by using powder sintering process and forming sintering process. A substance became a black ball with crystals and sparkles. The structures of the black ball have 2.4828 cm in diameter with a thickness of 0.372 cm and a density of 5.78 g/cm³. Next, we used the optical microscope to observe the surface before and after polishing. Before polishing, the surface characteristics were not clear crystals. After polishing, the surface characteristics were more clear crystals and shine. A black ball was measured by the Hall effect measurement method at -196 ° C to analysis of the electrical properties. The highest resistivity was 36.63 Ω·cm. The highest conductivity was 0.393 Ω·cm. Mobility maximum value of a black ball was 611.017 cm²/Vs.
