ABSTRACT:
A magnetic field sensor including a substrate supporting a magnetic layer having an easy axis of magnetization is manufactured by depositing the magnetic layer on the substrate in the absence of a magnetic orienting field, producing a structure in the layer in the form of a plurality of parallel equally large strips having an area of approximately 1/4 to 1/30 of the overall area of the magnetic layer, and subsequently subjecting the layer to a tempering process in a magnetic orienting field.
