1. Critical current and linewidth reduction in spin-torque nano-oscillators by delayed self-injection
Topic: Magnetics
Published: 6/15/2015
Authors: Guru Bahadur S Khalsa, Mark D Stiles, Julie Grollier
Abstract: Based on theoretical models, the dynamics of spin torque nano-oscillators can be substantially modified by re-injecting the emitted signal to the input of the oscillator after some delay. Numerical simulations for vortex magnetic tunnel junctions sho ...

2. Ultrafast Demagnetization Measurements using Extreme Ultraviolet Light: Comparison of Electronic and Magnetic Contributions
Topic: Magnetics
Published: 1/23/2012
Authors: Thomas J Silva, Justin M Shaw, Hans Toya Nembach, Margaret M. Murnane, Henry C. Kapteyn, Chan La-O-Vorakiat, Stefan Mathias, Emrah Turgut, Teale A. Carson, Martin Aeschlimann, Claus M. Schneider
Abstract: Ultrashort pulses of extreme ultraviolet light from high-harmonic generation are a new tool for probing coupled charge, spin, and phonon dynamics with element specificity, attosecond pump-probe synchronization, and time resolution of a few-femtosecon ...

3. 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 ...

4. Development of a multifilament PIT V3Ga conductor for fusion applications
Topic: Magnetics
Published: 6/12/2011
Authors: Najib Cheggour, Theodore C Stauffer, Loren Frederick 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 ...

5. Strain and Magnetization Properties of High Subelement Count Tube-type Nb3Sn Strands
Topic: Magnetics
Published: 6/6/2011
Authors: Najib Cheggour, X Peng, E Gregory, M Tomsic, M D Sumption, A. K. Ghosh, Xifeng Lu, Theodore C Stauffer, Loren Frederick Goodrich, Jolene D Splett
Abstract: Abstract,A tubular technique for economical production of Nb3Sn material with large numbers of subelements is being explored by Supergenics I LLC and Hyper Tech Research Inc. The number of subelements was increased to 919 (744 subelements plus 175 Cu ...

6. Electromagnetic Metrology on Concrete and Corrosion
Series: Journal of Research (NIST JRES)
Topic: Magnetics
Published: 6/1/2011
Authors: Sung Kim, Jack T 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 ...

7. Metrology of Microstructured Waveguides for Spintronic Applications
Topic: Magnetics
Published: 7/30/2010
Authors: SangHyun Lim, Atif (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 ...
