Current Annealing

We have studied effect of current annealing on domain wall dynamics of FeCoMoB microwires. It was showed that 10 minutes of current annealing corresponds to 1 hour of classical annealing in furnace. Moreover, electrical current flowing through microwire produces Oersted magnetic field and therefore circular magnetic anisotropy is induced during annealing. As a result, induced circular magnetic anisotropy prefers vortex domain wall with velocities up to 3 km/s that can be observed in the current annealed nanocrystalline FeCoMoB microwires with much higher temperature stability.

Domain Wall Velocity

Motion of an isolated domain wall in a double-layered magnetic film, whose layers differ in their uniaxial anisotropy only, is investigated through solving the Slonczewski equations by a numerical method. Dependences of the threshold field and the limiting velocity of disruption of the steady state motion of the film on the anisotropy and thicknesses of layers are obtained. Also, we showed that in domain wall unsteady motion regime, a dependence of domain wall velocity from magnetic field contains a series velocity peaks that relies on steady motion of Bloch lines across film and domain wall velocity in such cases can’t be simply increased by increasing magnetic field and restricted by some volume.
