Abstract

In an attempt to clarify the origin of the large critical current densities Jc observed in Laser Ablated and Sputtered YBa₂Cu₃O_7-δ (YBCO) thin films, we make a systematic study of the low temperature J_c in samples carefully analysed using STM and AFM. J_c (B) is determined from torque-magnetometry performed in ring-patterned thin films. Epitaxial YBCO films nucleate in e-axis oriented single-crystalline islands with sizes ranging between 200 and 700 nm. We show that J_c can be mainly explained by vortex pinning loealised in the island boundaries.
