The PROMAFAO project, funded by an ANR JCJC (2018-2022), is based on a collaboration between the MIMABADI (Mineralogy and Magnetism of Low Dimensionality) team of the IMPMC (UMR7590) and the CIN (Colloides INorganiques) team of the PHENIX laboratory (UMR 8234), located on the P. and M. Curie campus in Paris. The objective of the project is to understand the quantitative link between the magnetic and structural properties of so-called texturable ferrofluids. Since magnetic interactions between nanoparticles can lead to the appearance of assemblies that influence the macroscopic properties of ferrofluids, our strategy is to modulate these interactions by modifying the size, shape and composition of the nanoparticles and to study their influence on the magnetic properties. The recruited researcher will thus have the mission to synthesize in the PHENIX laboratory ferrofluids composed of ferrimagnetic nanospinels (MFe2O4, with M = Mn, Fe, Co, Zn) of various shapes (cube / sphere / flower / rod / bimagnetic core-shell), of size between 6 and 70 nm, and to characterize their morphological (size, shape), structural (crystallographic structure) and macroscopic magnetic properties. The texturable ferrofluids with the most spectacular / original properties will then be studied by the IMPMC using magnetic spectroscopies performed on synchrotron radiation facilities.


-Synthesis of magnetic colloids under different conditions (hydrothermal synthesis, microwave synthesis, ...) and by various processes (synthesis by co-precipitation, thermal decomposition or polyol process)
X-ray diffraction characterization, chemical titration, transmission electron microscopy, magnetometry measurements


PhD in chemistry or physico-chemistry
Good command of spoken, read and written English.
Good communication skills and ability to work in a team.
The candidate should demonstrate expertise in the synthesis of magnetic colloids by "classical" processes, as well as in their characterization. He (she) will be required to propose ideas and/or adapt the literature to achieve the synthesis of ferrofluids consisting of magnetic nanoparticles with original shapes.

Work Context

The work will be carried out within the CIN (Colloides INorganiques) team of the PHENIX laboratory (UMR 8234, Paris, Pierre and Marie Curie Campus of Sorbonne Université) in close collaboration with the MIMABADI (Minéralogie et Magnétisme de Basses Dimensionnalités team of IMPMC (UMR7590) located on the same campus.
