Magnetism and Electron Magnetic Resonance (MRME)



Our platform performs experiments in the field of materials chemistry but also in biology by implementing state-of-the-art electron paramagnetic resonance (EPR) and imaging techniques. We propose methodological developments, direct measurements of magnetic properties as well as measurements of numerous properties under magnetic field (electronic transport, thermal conductivity, thermoelectric effect...). We perform EPR measurements in continuous and pulsed mode on a variety of materials used in different research fields such as catalysis, energy storage and also in biological systems. We are open to all academic and industrial collaborations and propose services in line with our expertise.
