Magnetischer Speicher

摘要

The invention relates to a magnetic memory for binary data, such as has been produced up until now in the form of a hard drive or an interchangeable data support. The aim of the invention is to produce a predeterminable increase in the coercive force (Hc) of a magnetic memory in the appropriate magnetic layers. To this end, the magnetic memory has at least one ferromagnetic layer and an antiferromagnetic layer. The anti-ferromagnetic layer is made up of individual atomic monolayers which are antiferromagnetic in themselves and is of an appropriate thickness to cause a magnetic interaction which has an effect on the coercive force of the ferromagnetic layer. The coercive force (Hc) required can be adjusted in the ferromagnetic layer by varying the thickness of the antiferromagnetic layer. The antiferromagnetic layer has a cubic body centred structure with a crystal orientation in direction (110).
