FIG. 1.

Schematic of the energy barriers to reversal, showing the fractions of the energy barriers oriented parallel or antiparallel to the original set direction (a) and the unstable, set un, unset fractions within the AF layer (b).

FIG. 2.

Shift of the hysteresis loop after thermal activation at different temperatures in negative fields for IrMn/CoFe.

Image of FIG. 3.
FIG. 3.

field measured following the York protocol and measured via standard procedure for IrMn(3 nm)/CoFe. Solid lines are a guide to the eyes.

Image of FIG. 4.
FIG. 4.

field measured following the York protocol and measured via standard procedure for FeMn/NiFe. Solid lines are a guide to the eyes.

Image of FIG. 5.
FIG. 5.

Distribution of grain sizes and volumes for the FeMn(10 nm) layer. Lines calculated from experiment using Eq. (1).

Image of FIG. 6.
FIG. 6.

vs temperature of activation for FeMn, fitting and calculation of the anisotropy of FeMn following the AF grain volume model. [Line calculated from Eq. (4).]

Image of FIG. 7.
FIG. 7.

Fitting of Eq. (4) for the variation in with (upper curve). The lower curve shows the fit of with using Eq. (4) modified by Eq. (7) to allow for the temperature dependence of the interface spin ordering. Both fits use the same parameters for the bulk of the AF layer.
