Missions

The goal of this project is to study the effect of uniaxial strain on the structural and magnetic properties of a candidate for altermagnetism, Mn5Si3. This study combines laboratory techniques (specific heat, resistivity, ultrasound) and large scale facility techniques (neutron scattering at Institut Laue Langevin -ILL-). For some of these techniques, the project also involves to test and adapt existing strain cells to perform the required measurements. The candidate will work in strong collaboration with experts within Institut Néel, CEA Grenoble and the ILL. He will also strongly interact with a theorist at Institut Néel, expert in altermagnetism.

Activités

Principal tasks:
- Macroscopic measurements (specific heat, magnetization, resistivity)

- Experience in neutron scattering appreciated but not mandatory

Contexte de travail

The candidate will be part of the Magnetism and Superconductivity group at Institut Néel. This group involves more than twenty permanent researchers, and numerous students and postdoctoral associates. He will benefit from a stimulating and dynamic environment, with various scientific seminars organized at the Institute. He will also interact with scientists with diverse expertise within Institut Néel, CEA Grenoble and ILL.

The Institut NÉEL is a CNRS unit (UPR 2940) under agreement with the University Grenoble Alpes. The laboratory is related to the CNRS Physique. It is located in Grenoble, in the heart of a unique scientific, industrial and cultural environment. It is one of the largest French national research institutes for fundamental research in condensed matter physics enriched by interdisciplinary activities at the interfaces with chemistry, engineering and biology. It consists of 450 employees, including 175 researchers.

Le poste se situe dans un secteur relevant de la protection du potentiel scientifique et technique (PPST), et nécessite donc, conformément à la réglementation, que votre arrivée soit autorisée par l'autorité compétente du MESR.

Contraintes et risques

Radioprotection training and dosimetry will be provided to prevent the exposure risks associated to the neutron scattering experiments. Specific safety training will also be provided to prevent risks associated to cryogenics and high pressures.
