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

We report muon spin rotation studies on the magnetic properties of the newly discovered compound Ho12Co5Bi. We find that the material undergoes a bulk transition at TC ≈ 30 K to a magnetically ordered state. In the paramagnetic regime, we find slow

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 magnetic and superconducting behaviors of sintered Sr 2 YRu 1-u Cu u O 6 (for u=0.05, 0.10, 0.15) were probed using transverse- and zero-field muon spin rotation (μ+ SR). In general, positive muons are attracted to oxygen ions in the high-T c ox

The tunneling probability for a positive muon in high-purity tantalum is significantly enhanced by the onset of superconductivity. This establishes the predominant influence of low energy infrared couplings to the conduction electrons in the quantum

Cross relaxation between implanted positive muons and27Al nuclei in Al metal, lightly doped with Cu to impede the muon diffusion, shows weak resonances at 2.3 and 4.0 mT. Assignment of these to polarization transfervia the 1/2 ↔ 3/2 and 3/2 ↔ 5/2

The Co60Mu radical in polycrystalline C60 has been studied in zero magnetic field between 9 K and 200 K, and at room temperature. At low temperatures, we observe three low-frequency oscillations which correspond to the intra-triplet transitions of a

The procedure of zeugmatographic imaging — hitherto implemented only with nuclear magnetic resonance to form the well known MRI technique — is examined with the aim of utilizing it also in combination with non resonant phenomena. It is shown that

μLCR spectra from single-crystal Si∶Al have been taken at 30 K with the field along the 〈111〉 direction. The spectra show strong resonances near 12 and 50 mT, and weaker resonances near 38 and 42 mT. There is also indication of lines near 15 a
