摘要：

Sharp uncoupling of vortices from twin boundaries (TB's) at increasing inclination of the external field with respect to the TB plane is found by direct magnetooptic observations. Temperature dependence of the twin boundary pinning energy is determined from measurements of the critical angle of the field at which the above lock-in transition takes place.
