摘要：

Nd-123 single crystals have been produced via the Aux method in alumina crucibles by controlling the chemical composition of the flux. For so doing, quenched materials have been prepared and analyzed in order to get information about the optimum barium:copper ratio for an unchanged neodymium concentration. Non corrosive fluxes with a low viscosity have been put into evidence and can thus be used for single crystal production. Experiments have been performed with three different chemical compositions of the Aux and by considering various amounts of neodymium oxide for each system. The single crystals have been analyzed by energy dispersive X-ray microanalysis and used for the synthesis of large Dy-123 single-domains. (C) 1998 Elsevier Science Ltd. Ail rights reserved.
