3-D magnetic nanostructures

We investigated the influence of 3-D magnetic layer geometry on switching in magneto-electronic devices. We found that the 3-D topography of magnetic layer must absolutely be taken into consideration during the design phase since their inherent non-planarity profoundly affects their magnetization profile. Our initial results strongly indicate that the “non-flatness” of magnetic layer strongly influences the possible magnetic states, alters the switching mechanism and leads to totally new behavior, which was not observed in classic 2-D thin film magnetic structures. Our experimental results will be compared with detailed micromagnetic simulations.
