For small elements, this can be done using a single-macrospin theory since the element will switch quasi-uniformly. Experimental results on switching rates suggest that elements large enough to be thermally stable switch by some mechanism with a lower energy barrier. It has been suggested that this mechanism is local nucleation, but we have also previously reported a global magnetostatic instability, which is consistent with the lower experimen","authors_text":"Kamaram Munira, P.
