Voltage-Induced Magnetic Manipulation of a Microstructured Iron Gold Multilayer System — •Robert Sittig — Max Planck Institute for Intelligent Systems — Universität Stuttgart

This work was aimed at developing a microstructured system of ultra thin iron for voltage-induced magnetic manipulation.

For this purpose a layer sequence with capacitor geometry, based on a central MgO/Fe/Au-junction, is proposed. First, the quality of the materials, deposited on Si-substrate via sputter coating, is checked carefully with multiple characterization methods. Then a 5-step microstructuring pattern is designed for proper electronic connection. The corresponding lithographic processes are realized in a direct laser writer system and accordingly optimized. With the completed samples, the effect of static and pulsed electric fields on the magnetic film are studied in a MOKE microscope.

This work holds prospects for application in low-power spintronics and non-volatile data storage along with possible service as magnon source.
