Abstract:

This paper examines how nominally identical nanostructures can exhibit different switching behaviors in two model systems. The first system consists of an array of perpendicularly magnetized CoPd multilayer nanodots. The authors found that the nonuniformity in switching fields among the nanodots in an array is due to a single grain of weak uniaxial anisotropy. In the second system, which consists of inplane magnetized Permalloy nanodot arrays, they found that edge roughness plays an important role in the switching uniformity of the nanodot array.
