Stabilization of walls in notched ferromagnetic nanowires
Résumé
In this paper we study a one-dimensional model of ferromagnetic nanowire presenting notches. We prove the existence of stable wall profiles even under a small applied magnetic field with the walls localized in notches. Moreover, in order to illustrate wall depinning by applied magnetic field, we prove the non-existence of stationary wall profiles in the presence of a large applied magnetic field.
