21. Magnetic dynamics with spin transfer torques near the Curie temperature.
Topic: Electron Physics
Published: 9/24/2009
Authors: Paul M Haney, Mark D Stiles
Abstract: In this paper we explore the combined action of large thermal fluctuations and spin transfer torques on the behavior of magnetic layers in spin valves. We find that at temperatures near Tc, spin currents can measurably change the size of the magnet ...

22. Measurement of Small Birefringence and Loss in a Nonlinear Single-mode Waveguide
Topic: Electron Physics
Published: 5/11/2009
Authors: Daniel Rogers, Charles W Clark, Christopher Richardson, Julius Goldhar
Abstract: We design and fabricate a birefringent semiconductor waveguide for application to nonlinear photonics, demonstrating that it is possible to engineer a small birefringence into such a device using multiple core layers. We also demonstrate a simple t ...

23. A Bose-Einstein Condensate in a Uniform Light-Induced Vector Potential
Topic: Electron Physics
Published: 3/30/2009
Authors: Yu-Ju Lin, Robert L. Compton, Abigail Reiko Perry, William D Phillips, James V Porto, Ian B Spielman
Abstract: We use a two-photon dressing field to create an effective vector gauge potential for Bose-condensed ^87Rb atoms in the F=1 hyperfine ground state. The dressed states in this Raman field are spin and momentum superpositions, and we adiabatically load ...

24. Alignment of Fiducial Marks in a Tomographic Tilt Series with an Unknown Rotation Axis
Topic: Electron Physics
Published: 4/1/2007
Authors: Zachary H Levine, Peter Volkovitsky, Howard Hung
Abstract: Alignment for tomography using a transmission electron microscopy frequently uses colloidal gold particles as fiducial reference marks. Typically, there is an implicit assumption that the tilt axis of the tomographic series is orthogonal to the beam ...

25. Wake Fields in the Electron Gas, Including Transverse Response
Topic: Electron Physics

26. Progress on Spin Detectors and Spin-polarized Electron Scattering from Na at NIST
Topic: Electron Physics
Published: 1/1/1990
Author: Jabez J McClelland
Abstract: We provide a simple explanation, based on an effective field, for the precession damping rate due to the spin-orbit interaction. Previous effective field treatments of spin-orbit damping include only variations of the state energies with respect to ...

27. Use of Thorium as a Target in Electron Spin Analyzers
Topic: Electron Physics
Published: 4/1/1989
Authors: Jabez J McClelland, M Scheinfein, Daniel Thornton Pierce
Abstract: Measurements of the effective Sherman function have been carried out for 10-100-keV spin-polarized electrons scattering from a thick thorium target in a retarding Mott analyzer. At 20 and 100 keV the dependence on the maximum energy loss accepted by ...

28. Increased Sherman Function in Electron Spin Analyzers Using a Bulk Thorium Target
Topic: Electron Physics

29. Spin Sensitivity of a Channel Electron Multiplier
Topic: Electron Physics
Published: 3/1/1988
Authors: R E. Scholten, Jabez J McClelland, Michael H Kelley, Robert Celotta
Abstract: We report direct measurements of the sensitivity of a channel electron multiplier to electrons with different spin orientations. Four regions of the multiplier cone were examined using polarized electrons at 100-eV incident energy. Pulse counting and ...

30. Mott Scattering Measurements of the Spin Polarization of the NBS GaAs Electron Source
Topic: Electron Physics
Published: 4/6/1987
Authors: Jabez J McClelland, B Waclawski
Abstract: Measurements of the spin polarization of the GaAs electron source were carried out on the atom beam apparatus in the Electron Physics Group at the National Bureau of Standards. Both a cylindrical Mott analyzer operating at 100kV ("Maximott") and a h ...
