Abstract

We studied the effects of Pt and CeO₂ addition on the growth of Nd₄Ba₂Cu₂O₁₀ particles using three different starting materials: Nd123-Nd422, Nd422-BaO₂-CuO and Nd₂O₃-BaO₂-CuO, all having the same nominal composition of Nd:Ba:Cu = 1.8:2.4:3.4. It was found that both Pt and CeO₂ had beneficial effects on the size reduction of Nd422, although CeO₂ addition was more effective. Furthermore, it was also clarified that combined addition of Pt and CeO₂ was the most effective in refining Nd422 particles and thus increasing the J_C values at 77 K.
