Abstract

Magnetically coupled domain wall pinning has been investigated by means of an attached pair of ferromagnetic wires. The magnetic configuration of the paired wires (parallel or antiparallel) can be controlled by applying an external magnetic field along the wires. The strength of the pinning due to the magnetic interaction between the domain wall and the paired wires shows a significant difference between the parallel and antiparallel configurations, which is well reproduced by a micromagnetics simulation.
