Abstract

Dzyaloshinskii Moriya interaction (DMI) is currently the focus point of many research efforts in the spintronics community. Its possible applications and fundamental new physics motivate us to understand, measure and manipulate this interaction. DMI was demonstrated to influence domainwall motion, and more recently to influence magnetic nucleation [1]. We present an elegant, alternative experiment, which complements the ongoing research. By depinning a domain-wall from an anisotropy barrier in PMA nanowires in the presence of a static in-plane field, it is demonstrated that our samples exhibit DMI and a quantitative value for its strength is obtained.
