Abstract (en)
[origin: WO02084680A1] The invention is used in the field of materials engineering and relates to a method for defining reference magnetizations in layer systems that could be used, for example, in magnetic sensor technology components. The aim of the invention consists of providing a method for defining reference magnetizations in layer systems, whereby the reference directions can be selected as desired with regard to number and spatial direction. To this end, a method is provided for defining reference magnetizations in layer systems during which at least one layer system is produced by geometrically structuring a hard-magnetic and/or soft-magnetic layer and by applying the hard-magnetic and/or soft-magnetic layer to at least one antiferromagnetic layer before, during or after a single-stage or multi-stage thermal treatment, whereby the temperature is increased at least to a temperature greater than the coupling temperature, and the layer system is cooled afterwards.
