Abstract

We studied magnetic properties of a melt-textured Y-Ba-Cu-O with Y2BaCuO5 inclusions and a single crystalline YBa2Cu3Oy, grown by a crystal pulling technique by changing oxygen annealing conditions with the emphasis placed on the effect of doping level on flux pinning. Magnetization hysteresis loop measurements at 20 K and 77 K showed that the critical currents of the melt-textured sample were three times as large as those of a single crystal, which confirms the contribution of Y2BaCuO5 to pinning enhancement. In order to enhance flux pinning, it is important to introduce effective pinning centers in the good matrix with sufficiently large oxygen content.
