Abstract
Large domain YBCO are fabricated by using a melt processing technique for magnetic levitation applications. A Nd1+xBa2-xCu3Oy seed is used t o initiate grain growth and to control the orientation of YBCO grains. Samples as large as 50 mm diameter have been fabricated by utilizing this method. Microstructural studies reveals two distinct regions in t hese levitators due to different growth mechanisms along the a/b and c axes. Some initial result on the mass production of these levitators are also reported.
