Centre for Molecular and Materials Science

The Centre for Molecular and Materials Science (CMMS) provides unique tools for Canadian and international scientists to better understand matter at the microscopic level. We provide intense spin-polarized beams of muons (µ⁺ or µ⁻) and lithium-8 (⁸Li), which are implanted into a material and characterized with novel magnetic resonance techniques known as µSR (muon spin rotation / relaxation / resonance) and βNMR (beta-detected nuclear magnetic resonance). µSR and βNMR can provide unique information about a wide range of materials (magnetic systems, superconductors, semiconductors, batteries and free radicals) that is unavailable with conventional spectroscopic methods.
