The performance of CoFeB/MgO tunnel junctions is strongly dependent on an annealing step at the end of the fabrication process to first, set a reference magnetization through the exchange bias effect and second, to crystallize the MgO/CoFe layers whi

The performance of exchanged biased tunnel junctions strongly relies on the annealing process finalizing the fabrication process, which is applied to set a pinned reference magnetization, as well as to enhance the magnetoresistance ratio through the

In recent years, the selective laser structuring from the transparent substrate side plays an increased role in thin film processing. The rear side ablation is a highly effective ablation method for thin film structuring and revels a high structuring

The determination of the local field direction enables, for instance, migratory birds to find their annual routes from one continent to another, or magnetotactic bacteria to move towards soil rich in nutrients. In analogy, for microelectromechanical

Miniaturization is one of the main imperatives in high-tech development and therefore a persistent challenge for mechanical engineering. Recently a freeform technique – Laser Micro Sintering – has been developed by which micro parts with an overa
