Dependence of Exchange Coupling Interaction on Micromagnetic Constants in Hard/Soft Magnetic Bilayer Systems

September 1, 2007
Author(s)
Antonio Zambano, Hiroyuki Oguchi, Ichiro Takeuchi, Y W. Choi, J.S. Jiang, J P. Liu, S E. Lofland, Daniel Josell, Leonid A. Bendersky
To elucidate the dependence of exchange coupling behavior of hard/soft magnetic bilayer systems on various micromagnetic constants, the coupling length and the nucleation field (H (superscript_N)) were systematically measured on five thin film libraries

Free Space Antenna Factors through the Use of Time-Domain Signal Processing

September 1, 2007
Author(s)
Dennis G. Camell, Robert Johnk, David R. Novotny, Chriss A. Grosvenor
This paper demonstrates the usefulness of time-domain processing to determine free-space antenna factors (FSAF) for electromagnetic compatibility (EMC) antennas. Our procedures are explained and data are provided for frequencies from 30 MHz to 9GHz. We

Impact of Swapping Ethyl for Phenyl Groups on Diphosphine-Protected Undecagold

September 1, 2007
Author(s)
Justin Golightly, Lin Gao, A W. Castleman, Denis E. Bergeron, Jeffrey W. Hudgens, Rudolph Magyar, Carlos A. Gonzalez
1,3-Bis(diethylphosphino)propane (depp) protected gold clusters are synthesized and studied via electrospray ionization mass spectrometry. An undecagold cluster, [Au11(depp)4Cl2]+, is observed under soft ionization conditions, and is found to persist in

Inkjet Metrology and Standards for Ion Mobility Spectrometry

September 1, 2007
Author(s)
R M. Verkouteren, J Brazin, Eric S. Windsor, Robert A. Fletcher, R Maditz, Wayne Smith, John G. Gillen
Piezoelectric inkjet nozzles offer precise control for dispensing small quantities of materials. NIST is developing inkjet metrology to provide reference materials, calibration services, and other standards for the IMS detection of trace contraband

Integration of Incident Management Simulation-based Training Applications

September 1, 2007
Author(s)
Charles R. McLean, Yung-Tsun T. Lee, Sanjay Jain
The nation's incident management personnel and emergency responders need to work in a coordinated, well-planned manner to best mitigate the impact of natural and man-made disasters. They need to be trained and be ready to act in view of increased security

Issues with Imaging Drives Containing Faulty Sectors

September 1, 2007
Author(s)
James R. Lyle, Mark R. Wozar
In the ideal situation when imaging a hard drive, all sectors are completely and accurately acquired and saved to an image file. In reality, occasionally drives will contain faulty sectors such that the original content of the faulty sector cannot be

JOSEPHSON VOLTAGE STANDARD INTERCOMPARISON

September 1, 2007
Author(s)
Yi-hua Tang
The majority of Josephson Voltage Standard (JVS) intercomparisons have been performed by using Zener voltage transfer standards and a protocol based on the Measurement Assurance Program (MAP) with uncertainties in the range of a few parts in 10^8 at 10 V
