Abstract

The study with polarized neutron reflection showed the spatially resolved nuclear and magnetic structure in a high-temperature superconducting (HTc) film of YBa2Cu3O7 in the mixed state in an external field parallel to its surface. The obtained magnetic flux profile is composed of the penetrating Meissner field and the flux-line rows. The flux-line rows show good linear arrangements. A local critical magnetization inside the HTc film was determined. The total magnetization exhibits flux-line row transitions and increases in average with increasing external field due to the surface barrier and the flux-line interaction.
