✦ Synopsis

The melt-processed YBCO containing rare-earth 211-particles (Yb2BaCuOs) were synthesized with or without Pt-doping. A mixing of Yb and Y in the 211-phase occurs immediately after the incongruent melting of the 123-phase and proceeds during solidification. However, Pt-doping is found to suppress substantially the coalescence of the 211-particles and a mutual mixing of Y and Yb during the slow solidification process.

Bulk Y-Ho-Ba-Cu-0 and Y-Gd-Ba-Cu-G samples, which were prepared by a "powder melting process" (PMP) method, have been investigated. The results indicate that J, can be improved and the melting temperature may be changed by Ho and Gd substitution. In our samples the field dependence of J. is rather w
