1. Development of a multifilament PIT V3Ga conductor for fusion applications
Topic: Magnetics
Published: 6/12/2011
Authors: Najib Cheggour, Theodore C Stauffer, Loren F Goodrich, L. R. Motowidlo, J Distin, P. J. Lee, David C. Larbalestier, A. K. Ghosh
Abstract: Previous studies on V3Ga assert its suitability for use in proposed fusion reactors. V3Ga may outperform Nb3Sn in a fusion reactor environment based on its relatively flat critical-current profile in the 15 T- 20 T range, resilience to applied strain ...

2. Electrically Detected Magnetic Resonance in Dielectric Semiconductor Systems of Current Interest
Topic: Magnetics
Published: 5/1/2011
Authors: P. M. Lenahan, Corey Cochrane, Jason P Campbell, Jason T Ryan
Abstract: Several electrically detected magnetic resonance techniques provide insight into the physical and chemical structure of technologically significant deep level defects in solid state electronics. Spin dependent recombination is sensitive to deep level ...

3. Electromagnetic Metrology on Concrete and Corrosion
Series: Journal of Research (NIST JRES)
Topic: Magnetics
Published: 6/1/2011
Authors: Sung Kim, Jack Thomas Surek, James R. Baker-Jarvis
Abstract: To go beyond current electromagnetic nondestructive evaluation (NDE) methods for reinforcing bar (rebar) corrosion we are exploring unique magnetic or electric spectral features and whether these might be prominent enough at the concrete cover depth ...

4. Magneto-resistance based first order reversal curve analysis of magnetic tunnel junctions
Topic: Magnetics
Published: 7/13/2009
Authors: Joshua M Pomeroy, John Read, Theodore White, Holger Grube, Joseph E. Davies
Abstract: First order reversal curve (FORC) analysis is successfully applied to magnetic tunnel junctions (MTJs) by using the junction magneto-resistance (MR) instead of the magnetization field (M). FORC analysis is conventionally applied to magnetization vs. ...

5. Metrology of Microstructured Waveguides for Spintronic Applications
Topic: Magnetics
Published: 7/30/2010
Authors: SangHyun Lim, Atif Imtiaz, Dazhen Gu, Pavel Kabos, Thomas M Wallis
Abstract: Patterned permallay films as a part of a coplanar waveguide (CPW) were fabricated, and the magnetization dynamics of such structures was investigated as fundamental building blocks for magnetic spintronic devices. Anisotropic magneto-resistance (AMR ...

6. Multifunctional ferrimagnetic-ferroelectric thin films for microwave applications
Topic: Magnetics
Published: 6/20/2007
Authors: Ranko Heindl, S. Witanachchi, P. Mukherjee, A. Heim, G. Matthews, S. Balachandran, S. Natarajan, T. Weller
Abstract: Ferrimagnetic and ferroelectric structures based on barium strontium titanate and barium hexaferrite are investigated for potential applications in tunable microwave devices. Thin film bilayers were grown on MgO and sapphire, and their underlying c ...

7. Perpendicular ferromagnetic resonance measurements of damping and Landé g-factor in sputtered (Co^d2^Mn)^d1-x^Ge^dx^ thin films
Topic: Magnetics
Published: 8/8/2011
Authors: Thomas J Silva, Hans Toya Nembach, Justin M Shaw, Michael Schneider, Matt Carey, Stefan Maat, Jeff Childress
Abstract: X-ray diffraction (XRD), magnetometry, and ferromagnetic resonance (FMR) measurements were performed on sputtered thin films of the nominal Heusler alloy (Co^d2^Mn)^d1-x^Ge^dx^ with varying Ge content and annealing temperature. XRD indicates some deg ...

8. Spectroscopy and imaging of edge modes in Permalloy nanodisks
Topic: Magnetics
Published: 1/3/2013
Authors: Feng Guo, Lyubov Belova, Robert D McMichael
Abstract: This paper reports spectroscopy and imaging of spin wave modes using ferromagnetic resonance force microscopy (FMRFM) in Permalloy nano-disks with disk diameters that range from 100 nm to 750 nm. The ferromagnetic resonance spectra distinguish multip ...

10. Two dimensional spectroscopic imaging of individual ferromagnetic nanostripes
Topic: Magnetics
Published: 11/6/2012
Authors: Han-Jong H. Chia, Feng Guo, Lyubov Belova, Robert D McMichael
Abstract: We use ferromagnetic resonance force microscopy (FMRFM) to spectroscopically image the edge modes in individual 700 and 400 nm wide Permalloy stripes with a spatial resolution on the order of 200 nm. The imaging clearly identies some resonances as ...
