materials-research-at-psi

 

This is a collection of groups at PSI working on the creation, preparation and characterization of Materials with the tools available at PSI. We prepare bulk materials (single crystals and/or powders) or thin film systems. The structure of these materials is characterized with x-ray diffraction, transmission electron microscopy or neutrons. Magnetic characterization is performed with magnetometry, neutrons, muons or x-rays, and imaging with scanning probe microscopy, neutrons or x-rays. The experimental materials synthesis and characterization work is complemented by a strong efford to predict and describe theoretically materials and materials properties.
