Abstract
The energy barrier for thermally driven magnetization reversal in a two sec tion nanowire is calculated, based on a mechanism for domain wall nucleatio n at the interface between sections. It is shown that this energy barrier i s lower than that for end nucleation, and can be determined by choice of ma terial for each section.
