Abstract

The anisotropic magnetoresistance of single domain walls in S/F hybrid devices was studied with a view of examining the superconducting proximity effect at a single domain wall. By changing the geometry of a Py/Nb nanowire, the character of the domain wall that is nucleated can be controlled. The pinning of both vortex and transverse domain walls at narrow notches in the wires was investigated. In addition, the effect of the interfacial transparency between a superconductor and ferromagnet is also briefly discussed, showing a reduction of the superconducting proximity effect with poorer transparency.
