The activity focuses on the application of spectroscopic techniques such as continuous wave Electron Paramagnetic Resonance (EPR) and Mössbauer Spectroscopy as well as static and dynamic magnetic measurements to characterize materials. Studies with these techniques at low temperatures (typically, in the 4.2 - 300 K temperature range) can provide the interested users with invaluable information helping to identify key properties of their materials. As an example we mention the case of magnetic nanoparticles for biomedical applications such as pharmaceuticals and Magnetic Resonance Imaging contrast agents. The service is part of the activities of INNOVATION - EL.
