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