A granular level model of the magnetic properties of coupled ferromagnetic∕antiferromagnetic layers is used to calculate the temperature dependence of the exchange bias. The predicted results are in good qualitative agreement with experiment. Agreement with experiment requires the introduction of the temperature dependence of the anisotropy constant of the antiferromagnetic layer.
