FIG. 3.

Changes of of bilayers annealed at as a function of cumulative annealing duration, . Curves are the fitted calculation, based on the single spin ensemble model.

FIG. 4.

Conventional x-ray diffraction profiles (a) and grazing incident x-ray diffraction profiles (b) of bilayer, before (top) and after (bottom) thermal annealing at , . Asterisks index the diffraction peaks from silicon substrate.

Image of FIG. 5.
FIG. 5.

Schematic illustration of the single spin ensemble model for the AFM spins in FM/AFM bilayer and total free energy of AFM grains as a function of the angle of the AFM spin direction. While the bilayer includes huge number of AFM grains, only two AFM grains were illustrated as cylinders, for example. Black colored single-headed arrows indicate the surface spin of AFM grains, facing to the FM layer. Small springs labeled indicate the interfacial coupling strength. Double-headed arrows at the bottom of cylinders indicate the magnetic anisotropy axis of AFM grains, . The axis of each AFM grain is randomly oriented in the film plane.
