The effect of the antiferromagnetic spin flop on exchange bias has been investigated in antiferromagnetic (Formula presented)-ferromagnetic (Fe) bilayers. Cooling and measuring in fields larger than the antiferromagnetic spin-flop field, (Formula presented) causes an irreversible reduction of the magnitude of the exchange bias field, (Formula presented) This indicates that, contrary to what is normally assumed, the interface spin structure does not remain “frozen in” below (Formula presented) if large enough fields are applied. © 2000 The American Physical Society.
