摘要：

The magnetic flux density distribution in thin epitaxial YBaCuO films is detected using the magneto-optical Faraday effect. The external magnetic field is applied perpendicular to the film plane after zero field cooling. The results for the magnetic polarization, J, the critical current density, j(c), and the magnetic field, mu-0H*, of complete flux penetration are compared with SQUID magnetometer measurements. The flux density gradients as derived from the detected flux density distribution reveal the importance of the radial field in the investigated thin films with respect to the critical current density j(c) and the magnetic polarization J.
