Antiferromagnets are an exciting class of materials due to their inherently THz dynamics and complex interactions. Here, the highlight of our work is the demonstration that it is possible to switch the coupled antiferromagnet with a single femtosecond laser pulse. Our results provide a means of direct and deterministic control Read more…
Junta Igarashi received his Ph.D. from Tohoku University in 2021.During his Ph.D., thanks to the financial support of the Graduate Program in Spintronics, Tohoku University (GP-Spin), he had the opportunity to stay in Nancy as a research internship student, where he worked on all-optical switching in GdFeCo-based spin valves.Junta Igarashi Read more…

Designed for both adults and children aged 8 and up, “Magnetic” is an original exhibition created by the Jean Lamour Institute, a joint research Read more…
Jon Gorchon has been awarded the prestigious CNRS Bronze Medal for 2024. This year, the French National Centre for Scientific Research (CNRS) honored 48 exceptional researchers with the Bronze Medal, highlighting their significant contributions to advancing science. The CNRS Bronze Medal is awarded to researchers for their first major works Read more…
Thanks to a collaboration between IJL and SPINTEC laboratories we demonstrate that single pulse all optical switching is achieved in Co68Tb32/Co100-xGdx/Co68Tb32 tri-layers. The reversal behavior can be tuned from toggle to precessional switching by changing the composition of the Co100-xGdxalloy. More detail: Appl. Phys. Lett. 124, 022405 (2024)
A new study has shed light on how a thin layer of platinum with very high crystalline quality can convert the spin of electrons into electric current and vice versa. This phenomenon, known as spin-to-charge interconversion, is crucial for developing novel devices that use the spin of electrons for storing Read more…
Low-energy spin precession of electrons is observed in a thin film of cobalt-aluminum (CoAl). The precession angle can be controled via the strength of the molecular field. This behavior arises from the variation of the exchange field with temperature. We observe this phenomenon for electron energies between 0.9 and 1.2 eV. For more Read more…
As we bid farewell to another remarkable year, the Spin Team recently gathered for an unforgettable evening at “Grand Sérieux” to celebrate our annual End-of-the-Year Team Dinner. It was a night filled with joy, laughter, and sumptuous cuisine, marking the culmination of our hard work and successes throughout the year. Read more…
During his Phd V. Desbuis studied hot electrons transport. These electrons are extracted from a magnetic tunnel junction and injected into a metal base. Energy and wave-vector analysis was used to disentangle the different scattering contributions. Results are interpreted as being mainly influenced by inelastic scattering. An explicit transport model Read more…
On October 21st in Beijing Zongxia Guo and Hangtian Wang presented in front of an international jury their PhD work untitled “Electrical and optical manipulation of exchange bias “ and “Interfacial Engineering of the Magnetism in 2D Magnets, Topological Insulators, and Their Heterostructures “ respectively. The two Jury were impressed by the quality of the presentations Read more…
