We report a comprehensive muon spin rotation (μSR) study of the prototypical magnetoelectric antiferromagnet Cr_{2}O_{3}. We find the positively charged muon (μ^{+}) occupies several distinct interstitial sites and displays a rich dynamic behavior

The inverse perovskite Sr3SnO is a 3D cubic Dirac semimetal with a very small energy gap[1]. Its unusual electronic structure confers a variety of novel properties, such as chiral topological surface states, and very strong itinerant electron orbital

We report the β-detected NMR of implanted 8Li+ in the rhombohedrally distorted perovskite LaAlO3. As observed in other insulating perovskites, the resonance has large quadrupolar splitting. However, it exhibits additional splitting due to the rhombo

We perform detailed muon spin rotation (μSR) measurements in the classic antiferromagnet Fe_{2}O_{3} and explain the spectra by considering dynamic population and dissociation of charge-neutral muon-polaron complexes. We show that charge-neutral muo

We report measurements of the diffusion rate of isolated ion-implanted ^{8}Li^{+} within ∼120 nm of the surface of oriented single-crystal rutile TiO_{2} using a radiotracer technique. The α particles from the ^{8}Li decay provide a sensitive moni

A spectrometer for β-detected nuclear magnetic resonance (β-NMR) has been commissioned at the ISAC facility at TRIUMF. A beam of low energy highly spin polarized 8Li+ can be decelerated and implanted into ultra-thin structures 6–400 nm thick. β-

The polarized beam line at ISAC relies on the well known technique of collinear optical pumping to polarize the nuclear spins of a low energy (10–60 keV) radioactive beam. Alkali-metal beams are longitudinally polarized by optical pumping of a fast

We have measured the temperature dependence of the β-NMR resonances of 8 Li implanted in thin films of Au and Ag. At room temperature single narrow resonances are observed. The absence of appreciable quadrupolar splitting or broadening indicates tha
