Abstract

The effects of the amount of Bi₂O₃ and melting temperatures on the surface morphology of GdBCO films were studied. Films were observed to exhibit large island formations due to the addition of Bi₂O₃. Increasing the amount of Bi₂O₃ added enhances the melting of the sample, resulting to denser, more uniform surfaces and change in the grain structure of the island formations. Increasing the melting temperature naturally promotes the melting of the sample. A suitable melting temperature was found to be greater than 950^oC to avoid remnants of powder on the film surface. The film with 10 wt% Bi₂O₃ addition and melt quenched at 1000^oC exhibited the most favorable surface morphology compared to the other films.
