Missions

The candidate will explore Magneto-Chiral Dichroism (MChD), the differential absorption of light that chiral systems exhibit when irradiated with unpolarized light in a magnetic field with a unique home-made experimental setup. The aim is to identify the parameters governing the effect by comparing MChD with natural and magnetic circular dichroic (NCD and MCD) properties in specifically designed molecular systems and to demonstrate its interest for the readout of the magnetization in molecular chiral magnetic systems.

Activities

The candidate will perform Magneto-Chiral Dichroism measurements as a function of the temperature and the magnetic field on chiral systems of different morphologies (single-crystals, pellets, drop-casted samples) and he/she will develop the detection of MChD through light emission in the UV-Vis-NIR range on the Magneto-Chiral Dichroism spectrometer built-up in LNCMI. In parallel, she/he will be in charge of developing Natural and Magnetic Circular Dichroism (NCD and MCD) measurements on the same samples using a newly acquired cryogenic setup. A synthetic activity towards chiral magnetic molecular systems can be performed as a secondary activity.

Skills

- A PhD in Physical-Chemistry, in Condensed Matter Physics, in Material Science or in Chemistry.
- The candidate must have a strong experience in carrying physical/optical (magnetic/absorption/luminescence/dichroism) measurements and a solid scientific background.
- Competences in single-crystal X-ray diffraction (resolution, indexation) would be highly appreciated, as well as experience with cryogenic scientific instrumentation.
- A good English level is mandatory to participate actively to the team activity and the diffusion of the scientific results.

Work Context

The Laboratoire National des Champs Magnétiques Intenses is a CNRS large scale research infrastructure allowing researchers to carry out experiments in some of the most intense magnetic fields in the world. Continuous fields up to 36 T are available on the Grenoble site. Furthermore, unique experimental home-made setups are available for advanced physical measurements under magnetic field, such as the Magneto-Chiral Dichroism spectrometer that will be used by the candidate.
The candidate will work in the “molecular magnetism” research group strongly interacting with Prof. Cyrille Train, Dr. Matteo Atzori and Dr. Geert Rikken (LNCMI-Toulouse), and will collaborate with national and international research teams in the frame of already existing collaborations.

Constraints and risks

Individuals with pacemakers or medical implants who have contraindications to magnetic fields, are not permitted to work in this position due to health risks from the presence of strong magnetic fields.
