Arrangement for minimizing Neel interaction between 2 ferromagnetic layers separated by non-ferromagnetic layer compensates interaction with resultant magnetization of 2 layer systems
Arrangement for minimizing Neel interaction between 2 ferromagnetic layers separated by non-ferromagnetic layer compensates interaction with resultant magnetization of 2 layer systems
The arrangement has a first ferromagnetic layer forming a first sub-layer of a first asymmetrical artificial antiferromagnetic layer system in which the first sub-layer opposes a second at a distancing layer and the first sub-layer is thinner than the second. The second ferromagnetic layer is part of a similar antiferromagnetic layer system. The layer systems' resultant magnetization adds vectorially to compensate the Neel interaction. The arrangement has a first ferromagnetic layer (3) forming a first sub-layer of a first asymmetrical artificial antiferromagnetic layer system (13) in which the first ferromagnetic sub-layer opposes a second (5) at a distancing layer (4) and the first sub-layer is thinner than the second. The second ferromagnetic layer (11) forms a first sub-layer of a similar second asymmetrical artificial antiferromagnetic layer system (14). The total resultant magnetization of the layer systems adds vectorially in a Neel interaction-compensating manner.
