Positive exchange bias in FeF2-Fe bilayers.
We have discovered a positive unidirectional exchange anisotropy in antiferromagnetic (FeF2) and ferromagnetic (Fe) bilayers cooled through the antiferromagnetic critical temperature TN in large magnetic fields. For low positive cooling fields, the ferromagnet’s magnetization (M-H) loop center shifts to negative fields, as is normally observed in other systems. In contrast, large cooling fields...

متن کاملAntiferromagnetic 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...
