A periodic disturbance in local ferromagnetic ordering can propagate in a magnetic material in the form of a wave called a spin wave or a magnon. “Magnonics” is a field of research for the forthcoming beyond CMOS era; it harnesses magnons to transmit and process information using sophisticated spin wave devices and conduits. The standard spin wave conduits rely on spin waves in in-plane magnetized materials. There the spin waves are difficult to guide in curved conduits because of their anisotropic dispersion properties. Besides, miniaturization to deep sub-micron dimensions is a challenge as spin waves are sensitive to structural changes such as lithography-induced roughness at the conduit edges.

The ANR SWANGATE project has officially started with a kick-off meeting held at the Institut Jean Lamour (IJL) in Nancy. The aim of the project is to develop new magnonic devices based on spin wave channelling with magnetic domain walls. The project is coordinated by Prof. Michel Hehn at IJL and will involve researchers from the Institut de Physique et de Chimie des Matériaux de Strasbourg, Technische Universtität Kaiserslautern, and the NOMADE group.
The NOMADE group has an open position related to this project.
Congratulations to Dr. Myoung-Woo Yoo who recently received a two-year fellowship from 2016 call of the Marie Skłodowska-Curie Actions, which is funded by the Horizon2020 Framework Programme of the European Commission. Dr. Yoo will rejoin the NOMADE group in early 2018 to undertake a research project on the chaotic dynamics of nanocontact vortex oscillators. Well done!
