Notes:
Quasistatic magnetization switching of patterned 200 nm wide Ni81Fe19 elements has been systematically studied over a wide range of temperatures. In large aspect-ratio elements, the switching field between two bistable magnetization states decreases linearly as the temperature increases, in good agreement with thermally activated nucleation theory. In small aspect-ratio elements, however, switching occurs through a third stable state: the magnetization vortex state. Although the switching mechanism is drastically different in these small aspect-ratio structures, the switching fields also are linearly dependent on temperature. © 2001 American Institute of Physics.
