Query: Asymmetric magnetization reversal in exchange biased polycrystalline
  F/AF bilayers   This paper describes a model for magnetization reversal in polycrystalline
Ferromagnetic/Antiferromagnetic exchange biased bilayers. We assume that the
exchange energy can be expanded into cosine power series. We show that it is
possible to fit experimental asymmetric shape of hysteresis loops in exchange
biased bilayer for any direction of the applied field. The hysteresis asymmetry
is discussed in terms of energy considerations. An angle beta is introduced to
quantify the easy axis dispersion of AF grains.
