摘要：
We have studied the melt growth of Ag doped Gd-Ba-Cu-O (Gd123 + 40mol% Gd211 + xwt% Ag, x=0-10) bulks by using a cold-seeding method with Nd-Ba-Cu-O seed crystal. Growth temperatures of the Ag doped bulks decreased with increasing Ag contents. EPMA and magnetic measurements showed that Gd element diffused into the seed crystal and formed (Nd, Gd)123 composite at the interfacial region. The formation of the composite phase raised the growth temperature. For cold-seeding, therefore it is necessary to increase the growth temperature for the fabrication of large grain samples.
