Layer Resolved Magnetization Correlations in Multilayers

While magnetic multilayers can be regarded as systems that are artificially structured along one dimension, laterally patterned magnetic structures are systems that are structured, in addition, along a second (nanostripes) or third (nanodots) dimension. Fundamentally, novel properties analogous to the interlayer exchange coupling and the giant magnetoresistance effect in magnetic multilayers can be expected if the size of the structures become comparable to or smaller than certain characteristic length scales, such as the spin diffusion length, carrier mean free path, magnetic domain wall width, etc. [1]. Typically, those length scales lie in the several-to-hundreds nm range.
