Abstract
Digital magnetic memory cell device for read and/or write operations, having a soft-magnetic read and/or write layer system and at least one hard-magnetic reference layer system formed as an AAF system, comprising an AAF layer composite and at least one reference layer, the reference layer system comprising at least one ferromagnetic layer arranged adjacent to a magnetic layer of the AAF layer composite, in which case the thickness of the antiferromagnetic layer (10) is dimensioned in such a way that it has a uniaxial anisotropy.
