Layers developed by INNOVENT enable the production of magnetic nanostrips

07/07/2020

INNOVENT is mentioned in the current July Newsletter of the University of Vienna. The results of joint research projects obtained within the framework of European projects (ERC Starting Grant MagnonCircuits; A. Chumak), the Collaborative Research Center SFB 173 Spin+X (P. Pirro) of the German Research Foundation (DFG) and the DFG project DU 1427/2-1 (C. Dubs) were presented. Material base are single crystalline, epitaxial Yttrium-Iron-Garnet (YIG) layers developed by INNOVENT.

These layers , grown by Dr. C. Dubs in the Magnetic and Optical Systems Department, provide the basis for a development of innovative and particularly energy-saving computer chips due to the fact that information can be transmitted with minimal loss by using spin waves within these chips. YIG layers offer unique properties and have so far been used for millimeter-sized microwave structures. However, for wave-based signal processing, structures in the nanometer range have tob e achieved. Project leader Prof. Andrii Chumak and his team from the University of Vienna as well as junior professor Philipp Pirro from TU Kaiserslautern have now succeeded in successfully producing such nanostructures within a special structuring process. The research results were published in the journal Nano Letters (https://pubs.acs.org/doi/10.1021/acs.nanolett.0c00657).
