Effect of magnetostatic interactions on stochastic domain wall motion in sub-100-nm-wide nanowires. Siddiqui, S. A., Dutta, S., Currivan-Incorvia, J. A., Ross, C. A., & Baldo, M. A. IEEE Magnetics Letters, PP(99):1–1, 2017. doi abstract bibtex Magnetic field-driven domain wall motion is investigated in closely-spaced sub-100 nm wide Co concentric rings. We observe anti-correlations in the spatial distribution of pinning sites within weakly interacting nanowires, with a reduced probability of pinning adjacent to another pinning site over a mean correlation length similar to the line width roughness. In contrast, strong magnetostatic interactions between domain walls in adjacent nanowires eliminate the correlations, reducing the domain wall propagation distance for a given applied magnetic field.
