Exchange Bias Effect of Ferro-/Antiferromagnetic Heterostructures
Florin Radu,Hartmut Zabel +1 more
TL;DR: In this article, the most important models for the exchange bias effect are reviewed and the most recent experiments in the light of the presented models are discussed, as well as recent experimental results.

Exchange bias effect of ferro-/antiferromagnetic heterostructures
Florin Radu,Hartmut Zabel +1 more
TL;DR: The exchange bias (EB) effect was discovered 60 years ago by Meiklejohn and Bean as discussed by the authors and has become an integral part of modern magnetism with implications for basic research and for numerous device applications.

Evidence for core-shell magnetic behavior in antiferromagnetic Co3O4 nanowires.
M. J. Benitez,M. J. Benitez,Oleg Petracic,Elena-Lorena Salabas,Florin Radu,Harun Tüysüz,Ferdi Schüth,Hartmut Zabel +7 more
TL;DR: It is concluded that the nanowire shell behaves like a two-dimensional diluted antiferromagnet in a field.

Training-induced positive exchange bias in NiFe/IrMn bilayers.
TL;DR: Positive exchange bias has been observed in the Ni81Fe19/Ir20Mn80 bilayer system via soft-x-ray resonant magnetic scattering and this new manifestation of magnetic training is discussed in terms of metastable magnetic disorder at the magnetically frustrated interface during magnetization reversal.

Perpendicular exchange bias in ferrimagnetic spin valves
TL;DR: Taking advantage of the tunability of the exchange coupling between the ferrimagnetic layers by means of thickness variation of an interlayer spacer, it is demonstrated that perpendicular unidirectional anisotropy can be induced with desirable absolute values at room temperature, without making use of a field-cooling procedure.
