抄録

YBa<SUB>2</SUB>Cu<SUB>3</SUB>O<SUB>y-</SUB>Ag composite superconductor was synthesized by two kinds of methods, i.e., conventional ceramic and polymerized complex methods. There is almost no difference in the X-ray diffraction pattern between the samples prepared by the conventional ceramic and polymerized complex methods. The global pinning force F<SUB>p</SUB> of the samples prepared by the polymerized complex method is larger than that of the samples prepared by the conventional method. The transport critical current density J<SUB>c</SUB> of the samples prepared by the conventional ceramic method increases by the addition of Ag, while that of the samples prepared by the polymerized complex method is almost constant independent of Ag content. The values of F<SUB>p</SUB> and J<SUB>c</SUB> are much affected by the grain size and the distribution of Ag in the YBa<SUB>2</SUB>Cu<SUB>3</SUB>O<SUB>y</SUB> matrix.
