The behavior of magnets with submicron dimensions depends intimately on the magnets’ shape and size. The rich variety of resulting phenomena brings with it the promise of new technologies.
We are grateful to many colleagues whose advances have made patterned nanomagnets such a vibrant, exciting, and technologically relevant field. We thank Xiaochun Zhu of Carnegie Mellon University for useful exchanges and Oleg Tchernyshyov of the Johns Hopkins University for illuminating discussions and critical reading of this manuscript. We thank NSF for supporting our research.
