Abstract
We report a fabrication process of textured YBCO grown by seeded direc tional solidification using a MgO crystal as a seed, which alignes YBC O grains along c-axis with a texturing degree reduction as the distanc e from the seed increases. Measurements of magnetic hysteresis cycles were performed by means of vibrating sample magnetometry and the criti cal current density was estimated using Bean's critical state model.
