CRYSTALLINE MAGNETOTUNNEL JUNCTIONS: Fe - MgO - Fe , Fe - FeOMgO - Fe and Fe - AuMgOAu - Fe

We have modeled the electrical properties of three magnetotunnel junctions and find results similar to those in the literature. We have commenced investigations into the effects of perturbations to the exact positions of the atoms in these structures and report on the progress of these investigations.
