Contrasting impurity-induced magnetism and dynamics in 2H-MoTe2

Jonas A. Krieger, Igor P. Rusinov, Sourabh Barua +13

We investigate the behavior of interstitial $^{8}$ Li $^{+}$ implanted near the surface of 2H-MoTe $_{2}$ using $β$ -detected NMR. We find that, unlike the muon, $^{8}$ Li $^{+}$ does not show any…

Lithium-ion dynamics in synthetic quartz studied via the NMR of implanted $^{8}$ Li $^{+}$

W. Andrew MacFarlane, Ryan M. L. McFadden, Signy Spencer +11

We report $β$ -detected nuclear magnetic resonance ( $β$ -NMR) measurements of implanted $^{8}$ Li $^{+}$ in a synthetic single crystal of $α$ -SiO $_{2}$ (quartz). At 6.55 Tesla, the spect…

Ion-Implanted $^{8}$ Li Nuclear Magnetic Resonance in Highly Oriented Pyrolytic Graphite

John O. Ticknor, Jonah R. Adelman, Aris Chatzichristos +13

We report $β$ -detected nuclear magnetic resonance of ultra-dilute $^{8}$ Li $^{+}$ implanted in highly oriented pyrolytic graphite (HOPG). The absence of motional narrowing and diffu…

Investigation of Ionic and Anomalous Magnetic Behavior in CrSe $_{2}$ Using $^{8}$ Li $β$ -NMR

John O. Ticknor, Izumi Umegaki, Ryan M. L. McFadden +12

We have studied a mosaic of 1T-CrSe $_{2}$ single crystals using $β$ -detected nuclear magnetic resonance of $^{8}$ Li from 4 to 300 K. We identify two broad resonances that show no evi…

The dynamics of liquid 1-ethyl-3-methylimidazolium acetate measured with implanted-ion $^{8}$ Li $β$ -NMR

Derek Fujimoto, Ryan M. L. McFadden, Martin H. Dehn +14

We demonstrate the application of implanted-ion $β$ -detected NMR as a probe of ionic liquid molecular dynamics through the measurement of $^{8}$ Li spin-lattice relaxation (SLR) and r…
