Centre for Molecular and Materials Science
Next Proposal Deadline: May 2013
The goal of the Centre for Molecular and Materials Science (CMMS) is to provide tools for scientists to better understand matter at the microscopic level.
We provide intense spin-polarized beams of muons (µ+ or µ-) and lithium-8 (8Li+). These radioactive probes 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).
The CMMS facility was created to provide access for Canadian and international researchers to these powerful spectroscopic tools.
The Facility acquires, improves, and maintains a great variety of equipment with the aim to provide the the widest range of capabilities possible with the greatest interoperability and the least hassle. Facility personnel will set up the magnets, cryostats, counters, and electronic logic for an experiment. They are happy to consult in experiment design and apparatus upgrades.

The Luke (McMaster) and Uemura (Columbia) collaboration have used µSR to map out the magnetic phase digram of (Sr,Ca)2RuO4. The ground state has static magnetic order over nearly the entire range of (Ca, Sr) substitution and the magnetic phase diagram establishes the proximity of superconductivity in Sr2RuO4 to competing static magnetic order.

A team of researchers using the M15 beam line have found no evidence for previously reported magnetic monopoles in the spin ice material Dy2Ti2O7 (Bramwell et al. Nature 461 956 (2009)).
