1. A configuration for minimizing a Né
- el interaction, comprising;
a first asymmetrical artificial anti-ferromagnetic layer system having a first ferromagnetic sublayer, a second ferromagnetic sublayer, and a first spacer layer disposed between said first and second ferromagnetic sublayers;
a separating layer, said first ferromagnetic sublayer being oriented toward said separating layer and having a smaller layer thickness than said second ferromagnetic sublayer of said first asymmetrical artificial anti-ferromagnetic layer system; and
a second asymmetrical artificial anti-ferromagnetic layer system having a first ferromagnetic sublayer oriented toward said separating layer, a second ferromagnetic sublayer, and a second spacer layer disposed between said first and second ferromagnetic sublayers of said second asymmetrical artificial anti-ferrromagnetic layer system, said first ferromagnetic sublayer of said second asymmetrical artificial anti-ferromagnetic layer system having a smaller layer thickness than said second ferromagnetic sublayer of said second asymmetrical artificial anti-ferromagnetic layer system, and resulting total magnetizations of said first and second asymmetrical artificial anti-ferromagnetic layer systems being accumulated vectorially in a manner that compensates for the Né
el interaction between said first ferromagnetic sublayer of said first asymmetrical artificial anti-ferromagnetic layer system and said first ferromagnetic sublayer of said second asymmetrical artificial anti-ferromagnetic layer system each being oriented toward said separating layer.

Abstract
A configuration for minimizing and compensating for the Néel interaction between a first ferromagnetic layer and a second ferromagnetic layer on both sides of a nonmagnetic separating layer has an artificial anti-ferromagnetic layer system. The two ferromagnetic layers each being sublayers of an artificial anti-ferromagnetic layer system contribute to the minimization of the Néel interaction.
