ABSTRACT:
The present invention provides an MRAM that includes a conductive line for generating a magnetic field. The latter is enhanced by the addition of a flux concentrator made from a single plane of soft ferromagnetic material, magnetically stabilized by means of an antiferromagnetic layer. This structure, in addition to being very easy to fabricate, facilitates close control over its magnetic properties, including uniformity and domain structure.
