Avoided level crossing muon spin resonance (ALC-μSR) is used to characterize muoniated free radicals. These radicals are used as probes of the local environment and reorientational motion of specific components in complex systems. The parameter that

Fromsejer, R, Jensen, M L, Zacate, M O, Karner, V, Pecoraro, V L & Hemmingsen, L 2023, ' Molecular rotational correlation times and nanoviscosity determined by 111m Cd perturbed angular correlation (PAC) of γ-rays spectroscopy ', Chemistry: A European Journal, vol. 29, no. 9, e202203084 . https://doi.org/10.1002/chem.202203084
The nanoviscosity experienced by molecules in solution may be determined through measurement of the molecular rotational correlation time, τc, for example, by fluorescence and NMR spectroscopy. With this work, we apply PAC spectroscopy to determine

A new high field spectrometer has been built to extend the capabilities of the $\beta$-detected nuclear magnetic resonance ($\beta$-NMR) facility at TRIUMF. This new beamline extension allows $\beta$-NMR spectroscopy to be performed with fields up to

Using ion-implanted $^{8}\mathrm{Li} \ensuremath{\beta}$-detected NMR, we study the evolution of the correlated metallic state of ${\mathrm{LaNiO}}_{3}$ in a series of ${\mathrm{LaNiO}}_{3}/{\mathrm{LaAlO}}_{3}$ superlattices as a function of bilayer

We report $\ensuremath{\beta}\text{\ensuremath{-}}\mathrm{NMR}$ measurements in ${\mathrm{Bi}}_{2}{\mathrm{Se}}_{3}:\mathrm{Ca}$ and ${\mathrm{Bi}}_{2}{\mathrm{Te}}_{3}:\mathrm{Mn}$ single crystals using $^{8}\mathrm{Li}^{+}$ implanted to depths on t

We investigated the depth, temperature, and molecular-weight (MW) dependence of the γ-relaxation in polystyrene glasses using implanted 8Li+ and β-detected nuclear magnetic resonance. Measurements were performed on thin films with MW ranging from 1

We report $\ensuremath{\beta}$-detected NMR of ion-implanted $^{8}\mathrm{Li}$ in a single crystal and thin film of the strongly correlated metal ${\mathrm{LaNiO}}_{3}$. Spin-lattice relaxation measurements reveal two distinct local environments, bot
