Abstract
The characteristic relaxation frequency of a granular antiferromagnet f0 in the Néel–Arrhenius expression has been calculated from a high resolution measurement of the time dependence of the median blocking temperature of a CoFe/IrMn exchange biased system. Calculations based on a granular model give f0 = (2.1±0.4)×1012 s−1, three orders of magnitude greater than values commonly found in the literature.
