Description
We study the dynamics of domain walls in a notched ferro-magnetic nanowire. The model used is the Landau–Lifschitz equation in dimension 1, with a weight representing the notch. We highlight the pinning properties of notches, and the depinning properties of the applied magnetic field. In particular, we establish that when the applied field tends to push the wall far away from the notch, pinning effects are negligible.
