Coercivity and exchange bias of ferromagnetic/antiferromagnetic multilayers

For a model system consisting of a ferromagnetic layer exchange coupled to an antiferromagnetic layer with a compensated interface, detailed mean-field-type calculations are performed. Both the coercive field and the exchange bias field are calculated. For the coercive field, a rather broad enhancement around the Néel temperature TN of the antiferromagnetic layer is found irrespective of whethe...

Antiferromagnetic spin flop and exchange bias

The effect of the antiferromagnetic spin flop on exchange bias has been investigated in antiferromagnetic (MnF2) –ferromagnetic ~Fe! bilayers. Cooling and measuring in fields larger than the antiferromagnetic spinflop field, HSF , causes an irreversible reduction of the magnitude of the exchange bias field, HE . This indicates that, contrary to what is normally assumed, the interface spin struc...

Exchange bias effect of ferro-/antiferromagnetic heterostructures

The exchange bias (EB) effect was discovered 60 years ago by Meiklejohn and Bean. Meanwhile the EB effect has become an integral part of modern magnetism with implications for basic research and for numerous device applications. The EB effect was the first of its kind which relates to an interface effect between two different classes of materials, here between a ferromagnet and an antiferromagn...
