Non permanent researchers
The activities of the PMT group focus on the study and development of innovative materials with a dual objective, fundamental and applied.
- At a fundamental level, they deal with a better understanding of the physical properties of magnetic and thermoelectric materials.
- At an applied level, we seek to develop materials with novel properties by highlighting the relationship between their compositions and their physical properties, their structures and microstructures with a view to the design of alloys and nanostructured materials optimized for targeted applications. These are related to the domain of energy conversion such as thermoelectricity and the magnetocaloric effect, the optimization of permanent magnets, nano-medicine and the nano-environment.
The optimization of the intrinsic or extrinsic properties of these materials is achieved by the insertion of light elements or dopants, nanostructuring, control of microstructure or defects. These materials are characterized by techniques available in the laboratory such as X-ray diffraction, magnetic, electronic and thermal transport measurements, Mössbauer spectroscopy. In addition, studies on large instruments allow a finer characterization with X absorption, magnetic X-ray dichroism, resonant diffraction, neutron diffraction, measurements under a pulsed magnetic field.
These studies are also performed in connection with the activities of the “Modeling and Calculations” group for the modeling of magnetic and thermoelectric materials.
SrCuP et SrCuSb Zintl phases as potential thermoelectric materials
In this paper, we report the synthesis and the thermoelectric properties of SrCuP and SrCuSb. Good electronic properties associated to unexpected low thermal conductivity in this kind of structure gives its compounds promising ZT, making them interesting for thermoelectric applications.
