Abstract
The magnetic flux penetration in a high-quality YBa2Cu3O7-delta single crystal with an external field applied perpendicular to the crystalli ne c axis is directly visualised by means of the magneto-optical techn ique. The observations show that the field penetrates preferentially a long the ab planes. Scanning acoustic microscopy reveals macrodefects along ab planes which strongly affect this anisotropy of the field pen etration.
