Title:
DIGITAL MAGNETIC STORAGE CELL DEVICE
Document Type and Number:
WIPO Patent Application WO2002101751
Kind Code:
A3
Abstract:
The invention relates to a digital magnetic storage cell device for reading and/or writing operations that comprises a soft magnetic reading and/or writing layer system and at least one hard magnetic reference layer system. This reference layer system is configured as an AAF system and comprises an AAF layer composite and at least one reference layer. The AAF layer composite has two magnetic layers and the reference layer system has at least one antiferromagnetic layer, which is arranged adjacent to a magnetic layer of the AAF layer composite, whereby the magnetic layer (8) that is arranged at a distance from the antiferromagnetic layer (10) has a uniaxial anisotropy directed in a first direction. In addition, the magnetization of the antiferromagnetic layer (10) is aligned so that it is directed in a second direction. The anisotropy direction of the magnet layer (8) and the direction of magnetization of the antiferromagnetic layer (10) are located at an angle ( alpha ) to one another.
