Abstract

The study with polarized neutron reflection showed the spatially resolved nuclear and magnetic structure in a high-temperature superconducting (HT_c) 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 HT_c 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.
