Abstract
The properties of Bloch-type magnetic domain walls pinned in geometrical constrictions are studied using micromagnetic simulations. In agreement with the one-dimensional analytical model proposed earlier it is found that the wall width is reduced in constrictions smaller than the unconstrained wall width. However, the calculated wall type and its width differ quantitatively from those of the model. These differences are related to dipolar contributions and the possibility for the wall to bend outside the constriction. © 2004 Elsevier B.V. All rights reserved.
