Missions

The general aim of the work (project : PEPR RECYCLAGE-NTE) is to develop innovative methods for recycling rare-earth NdFeB magnets. To this end, an in-depth characterisation of recycled magnetic powders and sintered magnets obtained from these powders must be carried out. More specifically, the work will focus on scanning electron microscopy (SEM-EDS) and 57Fe Mössbauer spectroscopy. Transmission electron microscopy and tomographic atom probe tests may be considered on the most interesting samples.
The candidate will work in collaboration with CEA-LITEN and ICMCB, who will supply the samples to be analysed. He/she will be responsible for implementing the characterisation techniques and methods required for the project, as well as interpreting the results. He/she will monitor the project from a scientific and administrative point of view, working closely with the GPM team. He/she will be responsible for writing regular reports and deliverables describing the progress of the work. He/she will be required to add value to the work by writing publications and giving oral presentations.

Activities

- Implementation of characterisation techniques and interpretation of the data collected. Other techniques available in the laboratory may also be used, such as XRD, FTIR, Raman, SQUID
- Taking charge of any modifications to the analysis conditions in order to adapt to the nature of the samples
- Drafting analysis reports and project deliverables
- Regular presentations of results to project partners
- Drafting scientific publications or parts thereof, and presenting results at conferences
- Participating in the supervision of trainees recruited for the project
- Active participation in the day-to-day running of the laboratory

Skills

With a PhD in materials science and looking for a first fixed-term contract on completion of his/her PhD, the candidate should have good technical skills in characterisation by electron microscopy. Experience in the field of NdFeB magnets and knowledge of magnetism are desirable. He/she must be able to carry out Mössbauer analyses independently (preparing samples, adapting instruments for specific analyses, adjusting spectra).
Autonomous, rigorous and organised, the candidate will take part in regular project monitoring meetings. The ability to communicate and work in cross-disciplinary teams is important for the success of the project. Fluency of English for professional use is necessary.
The candidate will participate in project monitoring meetings which will be organized regularly. The ability to communicate and work in trans-disciplinary teams is important for the success of the project.

Work Context

This work will benefit from the prestigious framework of the future investment programme (PIA) France 2030 and more specifically from the PEPR programme (priority research programme and equipment) of the national strategy Recyclability, recycling and reincorporation of recycled materials. It will be carried out at the GPM laboratory (Groupe de Physique des Matériaux, UMR CNRS 6634), which is structured into five departments grouping 15 thematic teams: Scientific Instrumentation, Metallurgy-Microstructure-Mechanics, Functional and Nanostructured Materials, Disordered Systems and Polymers and Thematic Openings and Innovations. It has a staff of around 140, including 60 lecturers/researchers, 30 technical staff and 50 PhD students/postdoctoral fellows. The laboratory is located on the Rouen Normandy Science and Engineering Campus (Saint Etienne du Rouvray), within the Université de Rouen Normandie and INSA Rouen Normandie (7,000m2).
The researcher recruited will be attached to the Functional and Nanostructured Materials department and will work in close collaboration with the Supercritical Fluids group at ICMCB (Bordeaux) and the CEA-LITEN (Grenoble).

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.

Constraints and risks

The candidate will work in a restricted area to perform the Mössbauer analysis, due to the presence of the radioactive 57Co source. A radiation safety training will be delivered at the beginning of the position.
