Abstract
We demonstrate ratchet soliton propagation in individual patterned antiferromagnetically coupled superlattice elements down to 3 μm diameter using magneto-optical Kerr effect measurements. The bulk switching and soliton propagation fields are investigated as a function of the element size. It is found that on the length scale investigated here we do not see significant variation in ratchet behavior depending on the element size. The margin for soliton propagation and additional features related to downscaling are discussed.
