We are very pleased to announce that we have sign a research agreement with C12 Quantum Electronics (https://www.c12qe.com) C12 is a spin-off from the Physics Laboratory of the Ecole Normale Supérieure in Paris. In January 2020, twin brothers Matthieu and Pierre Desjardins officially launched the company to supercharge the development Read more…
In ” Les Échos” Victoire de Margerie, Vice Chairman of the World Material Forum (taking place June 16-18 2022 in Nancy https://worldmaterialsforum.com/home.html) is advocating for the use of Spintronic to reduce energy consumption and is reminding us that Albert Fert opened the field and received the Nobel Prize in 2007 Read more…
Anna will receive the Franco-German University Award (Prix Universitaire Franco-Allemand) on January 21st. The prize will be awarded to Anna in recognition for her master thesis work titled “Thin film materials with ultralow damping for novel magnonic phenomena”, which Anna conducted jointly between the TU Kaiserslautern (TUK) and Université de Read more…
Dr Junta Igarashi from Tohoku University is joining us for 2 years. He aims to pioneer ultra-fast (femto or picosecond regime) and high efficient magnetization manipulation by utilizing non-equilibrium state induced phenomena. He is funded by a Japan society for the promotion of science (JSPS) overseas research fellowship. https://www.jsps.go.jp/english/e-ab/index.html
Recently, we tried to get together and enjoy some outside time with all team members! Combined with petanque, barbeque and a sunny weather, we had a great time!
Ultrafast control of thin film nanomagnets using femtosecond laser pulses has attracted considerable attention for future ultrafast and energy-efficient photo-spintronics storage=memory devices. Single femtosecond laser pulse magnetization switching without an applied external magnetic field has been recently observed on various metallic thin films. Herein, a recent understanding of the physical Read more…
In collaboration with the “Laboratoire de physique et chimie théoriques” and the Max Born Institute, we theoretically investigated the effect of optical and extreme ultraviolet (XUV) circularly polarized femtosecond pulses on the magnetization dynamics of ferromagnetic materials. Relying on real-time time-dependent density functional theory, we demonstrated that the light induces Read more…
Thanks to the strong collaboration between Tohoku University, we investigated single-shot all-optical magnetization switching in a GdFeCo/Cu/[CoxNi1–x/Pt] spin-valve structure. We demonstrated that the threshold fluence for switching both the GdFeCo and the ferromagnetic layer depends on the laser pulse duration and the thickness and the Curie temperature of the ferromagnetic Read more…

In GdFeCo/Cu/CoPt spin valve, the ultrafast demagnetization of the ferrimagnetic GdFeCo alloy, generated by a single femtosecond laser pulse, is shown to generate enough spin current to switch the magnetization of the ferromagnetic CoPt multilayer. By increasing the Gd concentration, the CoPt switching is found to be more energy efficient. http://dx.doi.org/10.1002/advs.202001996 This work Read more…
