Effects of Different Fabrication Techniques on the Yttrium-Barium-Copper Oxide High Temperature Superconductor

Abstract

This study examines how several different parameters were changed in the yttrium-barium-copper oxide superconductor when the fabrication techniques were altered by using different barium precursors, including barium peroxide and barium carbonate; sintering at different temperatures, including 850, 900, 950 C; and annealing in an above ambient oxygen environment. Twelve different pellets were fabricated, and measurements were taken on them which included density, x-ray diffraction, critical temperature, critical current density, and magnetic susceptibility. The results showed that the barium perioxide derived samples had higher densities, better critical current densities and lower resistivities in the normal state. Keywords: Superconductivity, Yttrium-Barium- Copper oxide, High temperature superconductivity, Thesis.
