Abstract

Textured YBa₂Cu₃O_y(YBCO) bulk samples with Jc of magnitude of 10⁵ A/cm² were prepared by different melt procession (MP). Microstructure was examined by means of XRD, SEM and TEM. Very fine particles were observed by TEM. Transport critical current density, hysteresis and magnetization relaxation measurements for the samples show that the Jc and its field dependence vary significantly for the samples in LN ₂ and in fields up to 2 Tesla. The experiment shows that the quantity and quality of grain boundary is still very important for high Jc of MP YBCO.
