Néel Walls in Low Anisotropy Symmetric Double Layers
Carlos J. Garcı́a-Cervera · SIAM Journal on Applied Mathematics · 2005
A new model for the study of one-dimensional walls in magnetic multilayers is presented. We obtain the optimal scaling of this energy functional for low anisotropy double layers with magnetic layers of equal thickness. We prove that the optimal scaling may be attained by opposing Néel walls. We obtain the core length of the Néel wall and a detailed description of its structure. We illustrate our findings numerically.
