2. Spin transport parameters in metallic multilayers determined by ferromagnetic resonance measurements of spin-pumping
Topic: Physics
Published: 4/19/2013
Authors: Carl T Boone, Hans Toya Nembach, Justin M Shaw, Thomas J Silva
Abstract: We measured the spin-transport in nonferromagnetic (NM) metallic multilayers from the contribution to damping due to spin pumping from a ferromagnetic Co^d90^Fe^d10^ thin film. The multilayer stack consisted of NM^d1^/NM^d2^/Co^d90^Fe^d10^(2 nm)/NM^d ...

3. A critical compilation of energy levels, spectral lines, and transition probabilities of singly ionized silver, Ag II
Series: Journal of Research (NIST JRES)
Report Number: 118.009
Topic: Physics
Published: 4/15/2013
Author: Alexander Kramida
Abstract: All available experimental measurements of the spectrum of the Ag+ ion are critically reviewed. Systematic shifts are removed from the measured wavelengths. The compiled list of critically evaluated wavelengths is used to derive a comprehensive l ...

4. Shifts of optical frequency references based on spectral hole burning in Eu3+:Y2SiO5
Topic: Physics
Published: 3/6/2013
Authors: David R Leibrandt, Michael J. (Michael) Thorpe, Till P Rosenband
Abstract: Spectral hole burning laser frequency stabilization in Eu3+:Y2SiO5 is performed in a cryogenic environment with high temperature stability and low levels of vibration. Several properties of Eu3+:Y2SiO5 spectral holes are measured, including magnetic ...

5. Atom numbers in magneto-optic traps with millimeter scale laser beams
Topic: Physics
Published: 2/22/2013
Authors: Gregory William Hoth, Elizabeth A Donley, John E Kitching
Abstract: We measure the number of atoms, N, that can be trapped in a conventional vapor cell MOT using beams that have a diameter d in the range 1-5 mm. We show that the N \propto d^u3.6^ scaling law observed for larger MOTs is a robust approximation for opti ...

6. Cavity-stabilized laser with acceleration sensitivity below 10^u-12^/g^u-1^
Topic: Physics
Published: 2/21/2013
Authors: David R Leibrandt, James C Bergquist, Till P Rosenband
Abstract: We characterize the frequency-sensitivity of a cavity-stabilized laser to inertial forces and temperature fluctuations, and perform real-time feed-forward to correct for these sources of noise. We measure the sensitivity of the cavity to linear acce ...

7. Use of the Grand Canonical Transition-Matrix Monte Carlo Method to Model Gas Adsorption in Porous Materials
Topic: Physics
Published: 2/21/2013
Authors: Daniel W Siderius, Vincent K Shen
Abstract: We present grand canonical transition-matrix Monte Carlo (GC-TMMC) as an efficient method for simulating gas adsorption processes, with particular emphasis on subcritical gas adsorption in which capillary phase transitions are present. As in other a ...

8. A One-Kilogram Quartz Resonator as a Mass Standard
Topic: Physics
Published: 2/1/2013
Authors: David Allan Howe, J Vig
Abstract: The unit of mass, the kilogram, is the last remaining SI base unit defined by an artifact” [1]. This artifact, the primary mass standard, suffers from long term instabilities that are neither well understood, nor easily monitored [2]. A mass stand ...
