Superconducting properties of thin film studied via the NMR of implanted Li
Md Asaduzzaman, Ryan M. L. McFadden, Edward Thoeng +10
We report measurements of the normal-state and superconducting properties of thin-film using Li -detected nuclear magnetic resonance (-NMR). In…
Depth-resolved Characterization of Meissner Screening Breakdown in Surface Treated Niobium
Edward Thoeng, Md. Asaduzzaman, Philipp Kolb +12
We report direct measurements of the magnetic field screening at the limits of the Meissner phase for two superconducting Nb samples. The samples are processed with two different s…
Measurements of the first-flux-penetration field in surface-treated and coated Nb: Distinguishing between surface pinning and an interface energy barrier
Md Asaduzzaman, Ryan M. L. McFadden, Edward Thoeng +2
We report measurements of the first-flux-penetration field in surface-treated and coated Nb samples using muon spin rotation (SR). Using thin Ag foils as energy moderators for t…
Ion-Implanted Li Nuclear Magnetic Resonance in Highly Oriented Pyrolytic Graphite
John O. Ticknor, Jonah R. Adelman, Aris Chatzichristos +13
We report -detected nuclear magnetic resonance of ultra-dilute 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 -emitter Li
Ryan M. L. McFadden, Md Asaduzzaman, Terry J. Buck +11
We report measurements of the Meissner screening profile in a Nb(300 nm)/AlO thin film using Li -detected nuclear magnetic resonance (-NMR). The NMR probe $…
A New High Parallel-Field Spectrometer at TRIUMF's -NMR Facility
Edward Thoeng, Ryan M. L. McFadden, Suresh Saminathan +16
A new high field spectrometer has been built to extend the capabilities of the -detected nuclear magnetic resonance (-NMR) facility at TRIUMF. This new beamline extension all…
Nuclear magnetic resonance of ion implanted Li in ZnO
Jonah R. Adelman, Derek Fujimoto, Martin H. Dehn +14
We report on the stability and magnetic state of ion implanted Li in single crystals of the semiconductor ZnO using -detected nuclear magnetic resonance. At ultradilute conc…
Field of first flux entry and pinning strength of superconductors for RF application measured with muon spin rotation
T. Junginger, S. H. Abidi, R. Astley +9
The performance of superconducting radiofrequency (SRF) cavities used for particle accelerators depends on two characteristic material parameters: field of first flux entry $H_{ent…
Temperature-dependent and anisotropic optical response of layered PrCaMnO probed by spectroscopic ellipsometry
M. A. Majidi, E. Thoeng, P. K. Gogoi +9
We study the temperature dependence as well as anisotropy of optical conductivity () in the pseudocubic single crystal PrCaMnO using spectrocopic ellipso…
Interfacial tuning of perpendicular magnetic anisotropy and spin magnetic moment in CoFe/Pd multilayers
Duc-The Ngo, Z. L. Meng, T. Tahmasebi +6
We report on a strong perpendicular magnetic anisotropy in [CoFe 0.4nm/Pd t]6 (t = 1.0-2.0 nm) multilayers fabricated by DC sputtering in a ultrahigh vacuum chamber. Saturation mag…
