Thermal Limits on Field Alignment of Nanoparticle FePt Media

October 12, 2021
Author(s)
J A. Bain, William F. Egelhoff Jr.
We derive a simple expression for the angular distribution of ferromagnetic FePt particles an applied field in thermal equilibrium. This system is closely related to the Langevin expression for paramagnetic susceptibility, which computes the average

Thermal Properties of Pyroceram Code 9606

October 12, 2021
Author(s)
Daniel R. Flynn, James H. Yen, James J. Filliben, Robert R. Zarr, E M. Hohlfeld
In the late 1950s, Corning Glass Works measured the heat capacity, thermal diffusivity, and thermal expansion of Pyroceram Code 9606. In the early 1960s the National Bureau of Standards (NBS) measured the thermal diffusivity and the thermal conductivity of

Thin Film Edge Property Measurements by Edge Saturation

October 12, 2021
Author(s)
Brian B. Maranville, Robert McMichael, Cindi L. Dennis, C A. Ross, J Cheng
Two techniques are described for characterizing the magnetic properties of the edges in long, straight magnetic stripes, using vector magnetometry. The critical transverse field at which the edge magnetization saturates is determined by measuring

Thomas-Fermi approximation for double condensates

October 12, 2021
Author(s)
B D. Esry, C H. Greene, J P. Burke, J L. Bohn
We present calculations of the Thomas-Fermi wave functions for two simultaneously trapped and condensed hyperfire states of 87rb which has recently observed [C.J. Myatt,et al., Phys. Rev. Lett. (preprint)]. We show that the suppression of the spin exchange

Three-Dimensional Shape Analysis of Coarse Aggregates: Methodology and Preliminary Results on Several Different Coarse Aggregates

October 12, 2021
Author(s)
S T. Erdogan, P N. Quiroga, D Fowler, H A. Saleh, Richard A. Livingston, Edward Garboczi, Peter M. Ketcham, John G. Hagedorn, Steven G. Satterfield
The shape of aggregates used in concrete is an important parameter that helps determine many concrete properties. The mathematical technique of spherical harmonic analysis was recently demonstrated to be able to effectively analyze three dimensional

Tight-Binding Theory of Quantum Dot Arrays: InAs Dots

October 12, 2021
Author(s)
Javier Aizpurua, G C. Bryant, W Jaskolski
We model the electronic structure and optical properties of coupled self-assembled dots and period dot arrays by use of tight-binding theory. Coupling in dot molecules and dot arrays modifies significantly the level ordering and state symmetries. We show

Time-Domain Processing to Determine Free Space Antenna Factor

October 12, 2021
Author(s)
Dennis G. Camell, Robert Johnk
This paper demonstrates the usefulness of time-domain processing to determine free-space antenna factors (FSAF) for EMC antennas. Procedures are explained and data is provided from 30 MHz to 9 GHz. We investigate time gating of dense frequency packed
