Inversion of the domain wall propagation in synthetic ferrimagnets

In collaboration with colleagues at the Institut Jean Lamour (Nancy), we investigated domain wall propagation in synthetic ferrimagnets under applied magnetic fields. Depending on the relative alignment of the two component layers (parallel or antiparallel), different velocity versus field regimes are observed. This behaviour results from the competition between the external applied field and the interlayer coupling. This work has just appeared in Applied Physics Letters.

New ANR projects funded!

The NOMADE group has secured funding for two projects in the latest ANR Call for Projects:

  • Chaos-based information processing with magnetic nano-oscillators (CHIPMuNCS), which will be coordinated by Joo-Von Kim and involve colleagues at the Laboratoire Matériaux Optiques, Photonique et Systèmes (CentraleSupélec/Univ. Lorraine), Institut Jean Lamour (CNRS/Univ. Lorraine), and Unité Mixte de Physique CNRS/Thales.
  • Topological properties of magnetic skyrmions and opportunities for novel spintronic devices (TOPSKY), which will be coordinated by Vincent Cros of Unité Mixte de Physique CNRS/Thales and involve colleagues from the Laboratoire de Physique des Solides (CNRS/Univ. Paris-Sud), Institut Néel (CNRS/Univ. Grenoble), Laboratoire Charles Coulomb (CNRS/Univ. Montpellier), and the CEA Saclay.

SWANGATE project kicks off

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.

Kickoff meeting for the ANR Swangate project at the IJL, Nancy.

The NOMADE group has an open position related to this project.
