Abstract: The temperature dependence of the exchange bias in a bilayer ferromagnet-antiferromagnet system with an uncompensated surface has been calculated within the phenomenological Landau theory of phase transitions for the case where the Néel temperature of the antiferromagnet is close to and higher than the Curie temperature of the ferromagnet.
