We aimed to find the correlation between the structure of YBCO single crystals with their high Jc values (-105 A/cm2 at 77 K, zero magnetic field). The most remarkable feature which belongs to high-Jc crystals was found to be the presence of spirals on their surface. Detailed examination of the ion-
