Abstract

We have prepared (Nd,Sm,Gd)Ba2Cu3Oy "NSG-123" with various contents of (Nd,Sm,Gd)2BaCuO 5 "NSG-211" or Gd2BaCuO5 "Gd-211" with the aim of optimizing flux pinning. Microstructure observed by transmission electron microscopy exhibited a high density of RE-rich RE1+x Ba2-xCu3Oy (RE-123ss) clusters with their size and dispersion depending on the initially added 211 content. Gd-211 10 mol% distributed as small clusters ranging from 3 to 10 nm in size enhanced pinning at intermediate fields. The magnetization measurements suggested that the optimum oxygen pressure during melt-growth process for this system was around 1% pO2. It was confirmed that this material can be grown into single domain more then 40 mm in diameter.
