Abstract

The magnetic domain wall width of T-shaped permalloy structures has been measured using a photoemission electron microscope and x-ray magnetic dichroism. The results are compared to micromagnetic simulations. The shape of the structures allows us to analyze 90° Néel walls. We find a decrease in domain wall width with decreasing contact dimensions as expected by theory and in good agreement with our micromagnetic simulations
