Overview

abstract

• We have investigated the upper critical magnetic field (Formula presented) the critical current density (Formula presented) and the pinning force (Formula presented) in sputtered Nb/Pd multilayers, varying the temperatures (Formula presented) the Pd thicknesses (Formula presented) and the magnetic field (Formula presented) orientation (parallel and perpendicular to the plane of the sample). In perpendicular fields, the vortex dynamics was strongly influenced by grain-boundary pinning. In parallel fields, a peak was observed in the (Formula presented) curves for samples with Pd thicknesses (Formula presented) After comparing the experimental results with the existing theories, we have related the presence of this peak effect to the matching of vortex kinks with the layered artificial structure. © 1998 The American Physical Society.
