Voltage induced by domain wall motion in a ferromagnetic nanowire

ORAL

Abstract

We study current-induced domain-wall motion in a narrow ferromagnetic wire. This motion is described by effective equations of motion which depend only on four parameters. These parameters are set by the magnetic Hamiltonian and the shape of the wire. We propose a new way to measure these parameters by measuring time dependent voltage generated by the domain wall motion.
