Missions

This position is funded by the CLAMP (Couple functional Ligand Activation on Magnetic Particles) project. Its objective is to elucidate the dynamic properties of Fe3O4 ferrimagnetic nanoparticles (MNPs) functionalized by cobalt molecular complexes or azobenzene compounds.
The optical excitation of these ligands affects the magnetic anisotropy of the MNPs to which they are attached. As a result, grafting these organic ligands to MNPs is a promising strategy to improve the ultrafast optical control of their magnetization.
The recruited researcher will be tasked with investigating the ultrafast dynamics of magnetization and energy transfers within functionalized Fe3O4 nanoparticles induced by a laser pulse of duration less than 100 fs.

Activities

The successful candidate will perform optical pump-probe experiments on functionalized NPM arrays based on experimental parameters such as pump and probe pulse wavelengths, temperature, or applied magnetic field. The activity will also include the processing, analysis and interpretation of experimental data, participation in instrumental development and optimization of experimental protocols. The results obtained will be promoted by the writing of scientific publications and the presentation of the work at conferences. The successful candidate will interact regularly with the national partners of the CLAMP project. They will have to welcome partners from time to time during measurement campaigns and will participate in the supervision of interns or doctoral students.

Skills

The successful candidate will have strong skills in experimental ultrafast optics. In particular, an advanced expertise of optical pump-probe experiments is essential for this position. Magneto-optical skills will be appreciated. Good knowledge of condensed matter physics and magnetism is expected. Skills in experimental data processing, automation and computer modeling will be appreciated. The candidate must have a strong interest for experiences that require precision and time, a sense of teamwork and a good level of English (C1). Finally, they must be able to demonstrate rigorous organization.
An overall maximum experience of 2 years after phD is preferred

Work Context

This two-year position is funded by the French National Research Agency (ANR) as part of the CLAMP project of the LUMA Priority Research Program and Equipment (PEPR). The CLAMP project brings together six national partners, including the host team (FemtoMag) from the Institute of Physics and Chemistry of Materials in Strasbourg (IPCMS). IPCMS is a joint CNRS-University of Strasbourg unit whose research activity is highly interdisciplinary with three departments of physics and two of chemistry. The FemtoMag team is a specialist in ultra-fast magnetism and has four permanent researchers. The recruited candidate will have priority access to a state-of-the-art magneto-optical pump-probe experience using a 10 kHz amplified laser system with a sample environment at low temperature (He-free 3 K-300 K cryostat) and under magnetic field (0.7 T). The recruited researcher will have occasional access to the other experimental setups of the team.
__________
The site is located in a green setting and is easily accessible by public transport. The candidate (M/F) will have access to a nearby staff restaurant at a subsidized rate, a partial reimbursement of transport costs, and the social benefits offered by a works council. Teleworking is governed by a protocol, and annual leave and RTT days are set at 44.

The position is located in a sector under the protection of scientific and technical potential (PPST), and therefore requires, in accordance with the regulations, that your arrival is authorized by the competent authority of the MESR.
