Geometrical defect and magnetostatic coupling in multi-nanowire system.

We have found that when domain walls are present in two closely spaced nanowires, a Head-to-Head domain wall in one wire will be attracted to a Tail-to-Tail domain wall in the adjacent nanowire. Applying spin-polarized current to any of the nanowire in this case will move the two domain walls as a c...
