Abstract
The time dependence associated with the so-called exchange bias in coupled polycrystalline ferromagnetic/antiferromagnetic films has been suspected as arising from antiferromagnetic domain dynamics. In this paper we present a quantitative description of the nucleation and growth of antiferromagnetic domains based on the Kolmogorov-Avrami model, which describes the time dependence of the exchange bias in all the systems for which data could be found.
