Verfahren zur homogenen Magnetisierung eines austauschgekoppelten Schichtsystems einer digitalen magnetischen Speicherzelleneinrichtung

摘要

The invention relates to a method for homogeneously magnetizing an exchange-coupled layer system of a digital magnetic memory location device involving the use of an AAF (artificial antiferromagnetic) layer system and of an antiferromagnetic layer that exchange-couples a layer of the AAF layer system. When the direction of magnetization of the antiferromagnetic layer is determined, the magnetic layers of the AAF layer system are saturated in a magnetic field and, afterwards, the direction of the antiferromagnetic layer magnetization and the direction of the saturated magnetic field are changed with regard to one another whereby being at an angle alpha of 0 DEG < alpha < 180 DEG with regard to one another whereupon the saturating magnetic field is switched off.
