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…

Depth-resolved measurement of the Meissner screening profile in a niobium thin film from spin-lattice relaxation of the implanted $β$ -emitter $^{8}$ Li

Ryan M. L. McFadden, Md Asaduzzaman, Terry J. Buck +11

We report measurements of the Meissner screening profile in a Nb(300 nm)/Al $_{2}$ O $_{3}$ thin film using $^{8}$ Li $β$ -detected nuclear magnetic resonance ( $β$ -NMR). The NMR probe $…

Bi-Arrhenius diffusion and surface trapping of $^{8}$ Li $^{+}$ in rutile TiO $_{2}$

A. Chatzichristos, R. M. L. McFadden, M. H. Dehn +11

We report measurements of the diffusion rate of isolated ion-implanted $^{8}$ Li $^{+}$ within $\sim$ 120 nm of the surface of oriented single-crystal rutile TiO $_{2}$ using a radiotrac…
