ABSTRACT Multi-seeded YBCO superconductors (cylindrical size) 32 mm in diameter were fabricated by top-seeded melt growth
(TSMG). Melt-processing was performed using a precursor containing 75 wt % of Y123 and 25 wt % of Y211 with 0.5 wt % of
CeO2. Trapped magnetic field at 77 K of the multi-seeded bulk samples (single grain and two grains) were studied. The maximum
trapped field measured at the top and bottom surface of single grain YBCO 32 mm in diameter were as 0.56 and 0.55 T at 77 K,
respectively. Trapped field measurements on the top and bottom surfaces of the (100) // (100) aligned samples were measured
and as the value of d increases, trapped magnetic field decreases.
