Research themes

Intermetallics: from synthesis to physical properties

The "Intermetallics" research topic at ISCR-CSM is focusing on two main axes:

- Uranium based intermetallics: from fundamental properties to application to nuclear materials

The solid state chemistry of uranium compounds started in the 1950's in Rennes and was continuously developed till now.

In our group, we investigate ternary U-T-X phase diagrams where T is a transition metal and X a p-block element, trying to discover new phases with exotic physical properties such as heavy fermion behaviour, coexistence of superconductivity and (ferro)magnetic ordering, magnetic frustration,... We try to establish the relation between the chemical composition, the crystal structure (determined by single crystal X-ray diffraction) and the basic magnetic, electrical and specific heat properties of the new phases. In the last years, we implemented the single crystal growth by chemical methods (mainly the metal flux one) to further characterize the influence of the crystalline anisotropy on the physical properties. X-ray absorption spectroscopies (Dr. Carmelo Prestipino) and neutron diffraction experiments (Dr. Pierric Lemoine) are used to look deeper in the electronic structure of these compounds.

This work is often performed through international collaborations with solid state chemists of the Center for Nuclear Sciences and Technologies (Prof. A. Gonçalves) in Lisbon (Portugal) and physicists from the Institute of Low Temperature and Structure Research (Dr. A. Pikul and Prof. D. Kaczorowski) from Wroclaw (Poland).

Our expertise in the chemistry, reactivity and properties of uranium intermetallics applies to nuclear materials, e.g. to understand the interactions between a material and  its matrix in nuclear fuels, to develop innovative materials for medical irradiation targets or to propose new synthesis/shaping techniques for improved preparation of such materials. This activity is develop in collaboration with CEA Cadarache or Framatome-Cerca.
