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...

Exchange Bias in Fe0.6Zn0.4F2 Heterostructures

The exchange bias field, He; is measured in Fe0.6Zn0.4F2/Fe heterosystems prepared from Fe layers of 14 and 5 nm thickness which are deposited on top of the compensated (1 1 0) surface of the antiferromagnet. Deviations from a linear dependence of He on the magnetization of the Fe layer are attributed to ferromagnetic domains. Moreover, piezomagnetism and its influence on He are evidenced. r 20...

Training of the exchange-bias effect in NiO-Fe heterostructures

Electric-field control of exchange bias in multiferroic epitaxial heterostructures.

The magnetic exchange between epitaxial thin films of the multiferroic (antiferromagnetic and ferroelectric) hexagonal YMnO3 oxide and a soft ferromagnetic (FM) layer is used to couple the magnetic response of the FM layer to the magnetic state of the antiferromagnetic one. We will show that biasing the ferroelectric YMnO3 layer by an electric field allows control of the magnetic exchange bias ...
