Abstract

A direct measurement of the distance between the vortices was performed by neutron surface diffraction. The vortices were created by an external magnetic field H_ext parallel to the surface of a thin YBa₂Cu ₃O₇ film. The behavior of the equilibrium vortex configurations in increasing H_ext beyond the first critical field was studied. The distances between vortices within the vortex rows parallel to the sample surface were deduced from the positions of the Bragg-peaks measured in grazing incidence configuration GID for H_ext = 1.0 and 1.5T. The obtained values of the distance of 445 and 480 Å, respectively, belong to the equilibrium configurations with four and five vortex rows perpendicular to the film surface.
