Characterization of Ternary Compounds in the BaO:Fe 2 O 3 :TiO 2 System: Ba 6 Fe 45 Ti 17 O 106 and BaFe 11 Ti 3 O 23

January 1, 1999
Author(s)
Terrell A. Vanderah, Winnie K. Wong-Ng, B H. Toby, V. M. Browning, Robert D. Shull, Richard G. Geyer, Robert S. Roth
Single crystals of Ba 6Fe 45Ti 17O 106 and BaFe 11Ti 3O 23 were obtained as major and minor co-products, respectively, by slow-cooling an off-stoichiometric BaO:Fe 2O 3:TiO 2 melt. The former compound exhibits variable stoichiometry Ba 6Fe 48-xTi 14+xO 106

Application of NMR-based Metabolomics for Environmental Assessment in the Great Lakes using Zebra Mussel (Dreissena polymorpha) polymorpha)

February 21, 2015
Author(s)
Miki Watanabe, Katherine Meyer, Tyler Jackson, Tracey Johnston, Ed Johnson, Dan Bearden
Zebra mussel, Dreissena polymorpha, in the Great Lakes is being monitored as a bio-indicator organism for environmental health effects by the National Oceanic and Atmospheric Administration's Mussel Watch program. In order to monitor the environmental

Spin-Wave Propagation in the Presence of Interfacial Dzyaloshinskii-Moriya Interaction

November 4, 2013
Author(s)
Jung-Hwan Moon, Soo-Man Seo, Kyung Jin Lee, Kyoung-Whan Kim, Jisu Ryu, Hyun-Woo Lee, Robert McMichael, Mark D. Stiles
In ferromagnetic thin films, broken inversion symmetry and spin-orbit coupling give rise to interfacial Dzyaloshinskii-Moriya interactions. Analytic expressions for spin-wave properties show that the Dzyaloshinskii-Moriya interaction leads to non

Accuracy and Reproducibility of X-Ray Texture Measurements on Thin Films

May 1, 2002
Author(s)
Mark D. Vaudin, G R. Fox, G -. Kowach
Rocking curve texture measurements were made on thin films of zinc oxide (ZnO) and platinum (Pt) using a powder x-ray diffractometer, and also, in the case of ZnO, an area detector. The intensity corrections for defocussing and other geometric factors were

Field-free ringing of nanomagnets

July 1, 2007
Author(s)
Thomas J. Silva
Ever since William Gilbert's 16th century treatise "De Magnete," it has been known that magnetic fields can be used to manipulate the magnetic orientation of ferromagnets. This has been the foundation for electronic applications of magnetic materials for

Chip-Scale Atomic Magnetometers

December 1, 2004
Author(s)
P Schwindt, Svenja A. Knappe, V Shah, Leo W. Hollberg, John E. Kitching, Li-Anne Liew, John M. Moreland
Using the techniques of micro-electro-mechanical systems, we have constructed a small, low-power magnetic sensor based on alkali atoms. We use a coherent population trapping resonance to probe the interaction of the atoms' magnetic moment with a magnetic

Synthetic Mica: A Very Promising Substrate for Studying Solid Thin Films by Proton NMR

August 25, 2009

David L. VanderHart, Vivek M. Prabhu, Kristopher Lavery, Cindi L. Dennis
We demonstrate that a synthetic fluorophlogopite mica can be used as a proton-free, diamagnetic substrate for examining solid thin-film samples using conventional solid-state proton NMR experiments. The context of this work extends previous NMR studies on

Metrology of Microstructured Waveguides for Spintronic Applications
