Abstract:

I will present recent results using beta-detected NMR which uses short-lived radioisotopes as implanted  NMR probes of solids. In betaNMR, the signal is detected through the radioactive beta decay. This "nuclear" detection scheme vastly enhances the signal per probe spin, enabling measurements that are not possible with conventional NMR, such as studying nanometric thin films. Our primary probe is the heavy isotope 8Li, but I will also discuss some new results using 31Mg.
