Relation of domain properties to structural changes in perpendicularly magnetized ultrathin films

The influence of interface mixing upon the magnetic domain properties in perpendicularly magnetized ultrathin films has been studied using Fe/2 ML Ni/W(110) samples. Annealing of films with an Fe thickness of 1–1.5 ML produces interface mixing that can be quantified using Auger electron spectroscopy, and related to the changes in domain properties (such as the activation energy for domain wall pinning, the domain correlation length, and domain …
