Abstract
A method and apparatus for homogeneously magnetizing an exchange-coupled layer system of a digital magnetic memory cell device comprising an AAF layer system and an antiferromagnetic layer that exchange-couples a layer of the AAF layer system, characterized in that, given a defined direction of magnetization of the antiferromagnetic layer, the magnetic layers of the AAF layer system are saturated in a magnetic field and, afterward, the position of the direction of the antiferromagnetic layer magnetization and the direction of the saturating magnetic field relative to one another is changed, so that they are at an angle .alpha. of 0.degree.<.alpha.<180.degree. relative to one another, after which the saturating magnetic field is switched off.
