|
| The basic premise is that a legacy part design that was originally optimized for one manufacturing process may either be impossible to produce by another process, or too costly. To re-manufacture a replacement part, the original geometry and the material need to be modified; such modification must be done without violating the inter-facing, functional and structural constraints. The Rapid Re-Engineering System (RRES) is envisioned to serve as a bridge. |

| 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 Co/Pd 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 ... |
