N2 - A tilt angle dependence of vortex structure was studied at low-angle grain boundaries (LAGBs) in Y Ba2 Cu3 O7-x films. The 2°tilt LAGB did not degrade Jc of the film in a self-field, demonstrating the existence of Abrikosov vortices at the 2° LAGB. The magnetic field dependence of the flux flow resistance indicated the existence of Abrikosov Josephson vortices at the 5° tilt LAGB. At the 10° tilt LAGB, a Josephson junction behavior was observed in a self-field, indicating the existence of Josephson vortices. The influence of the LAGBs on critical current density was understood based on these vortices.
