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.
