Abstract

A new direct observation method for the dynamical magnetic flux behavior in superconductors was developed by using the Faraday effect of an iron garnet film with perpendicular magnetization and stripe domains. The domain structure observed optically in the iron garnet film in contact with an YBa2Cu3Ox sample reveals the magnetic field distribution of the latter. It was found that the flux gradient was nonuniform due to the inhomogeneous distribution of fine Y2BaCuO5 inclusions, and the region with the largest pinning force was located in the sample used.
