FIG. 10.

Fits of the Néel-Brown model Eq. (A1) to the uncoupled SMTJ transistion rates ${\text{Γ}}_{\pm }$ (e.g. Fig. 2) at four different source voltages. Error bars indicate single standard deviation uncertainties due to the imprecision in setting the applied field value and the statistical uncertainty due to the limited number of transitions recorded for each point.
