360° domain wall injection into magnetic thin films
AL Gonzalez Oyarce, J Llandro… - Applied Physics Letters, 2013 - pubs.aip.org
We used micromagnetic simulations to develop a device for the injection of localised 360
domain walls into a magnetic thin film nanostripe. In our simulations two current profiles,
step and staircase, are applied to two non-parallel wires placed in close proximity to, but not
in electrical contact with, the magnetic nanostripe. We show that for current densities of∼ 10
12 A/m 2 and experimentally achievable device dimensions, the magnetic fields generated
by these current pulses are of sufficient strength to cause the nucleation of stable and …
