Improved Interfaces and Magnetic Properties in Spin Valves Using Ni 80 Fe 20 Seed Layer

March 1, 2002
Author(s)
E J. Repetski, D X. Yang, H D. Chopra, P J. Chen, William F. Egelhoff Jr.
The giant magnetoresistance (GMR) (Ni 80Fe 20)O-Co-Cu based top spin valves were studied with and without Ni 80Fe 20 as a seed layer. Microstructure examination shows that without the seed layer, the free and the pinned Co layers of the spin valves are

Improved Interfaces and Magnetic Properties in Spin Valves Using Ni80Fe20 Seed Layers

E J. Repetski, D X. Yang, H D. Chopra, P J. Chen, William F. Egelhoff Jr.
The giant magnetoresistance (GMR) NiFeO-Co-Cu based top spin valves were studied with and without NiFe as a seed layer. Microstructure examination shows that without the seed layer, the free and the pinned Co layers of the spin valves are highly irregular

In Situ Raman Spectroscopic Investigation of Nickel Hydrothermal Corrosion

March 1, 2002
Author(s)
James E. Maslar, Wilbur S. Hurst, Walter J. Bowers Jr., Jay H. Hendricks, M I. Aquino
A nickel coupon was exposed to air-saturated water at a pressure of 25.4 MPa and temperatures ranging from 21 C to 460 C in an optically accessible flow cell. In situ Raman spectra were collected at a number of temperatures as the coupon was heated and

In the Rough

March 1, 2002
Author(s)
Theodore V. Vorburger, Joseph Fu, N G. Orji
Surface roughness affects the function of a wide variety of engineering components, including airport runways, highways, ship hulls and mechanical parts. Perhaps the most demanding applications are in the optics and semiconductor industries. Surface

Influence of Dendrimer Additives on the Dewetting of Thin Polystyrene Films

March 1, 2002
Author(s)
M E. Mackay, Y Hong, M Jeong, S Hong, T P. Russell, C J. Hawker, R Vestberg, Jack F. Douglas
A small mass concentration of poly(benzyl ether) dendrimer added to a low molecular mass polystyrene is found to inhibit the dewetting of a thin ( 50 nm) polystyrene film from an acid etched silicon substrate. The inhibition effect is found to depend on

Issues and Applications in Ultrasensitive Molecular Spectroscopy

March 1, 2002
Author(s)
C Ishibashi, Jun Ye, John L. Hall
We present a systematic analysis of ultra-sensitive molecular detection methods based on an optical cavity and frequency modulation spectroscopy. Our goal is towards the improvement of the limiting attainable performance by the choice of optical

Knowledge-Based Automation of a Design Method for Concurrent Systems

March 1, 2002
Author(s)
Kevin L. Mills, H Gomaa
This paper describes a knowledge-based approach to automate a software design method for concurrent and real-time systems. The approach uses multiple paradigms to represent knowledge embedded within the design method. Semantic data modeling provides the

Local Imaging of Photonic Structures: Image Contrast From Impedance Mismatch

March 1, 2002
Author(s)
A L. Campillo, Julia W. Hsu, Garnett W. Bryant
Photonic structures constructed from square arrays of air holes in Si 3N x membranes are locally imaged by near-field optical microscopy in illumination mode. Holes with diameters smaller than and larger than the wavelength of light are investigated

Local-Field Correction for an Interstitial Impurity in Crystal

March 1, 2002
Author(s)
A Rahmani, P C. Chaumet, G C. Bryant
The local-field correction experienced by an interstitial impurity in a crystal with cubic symmetry is derived by use of a rigorous, self-sonsistent, semi-microscopic description of spontaneous emission in a microcavity. We compute the local-field factor

Mathematical Software: Past, Present, and Future

March 1, 2002
Author(s)
Ronald F. Boisvert
This paper provides some reflections on the field of mathematical software on the occasion of John Rice's 65th birthday. We describe some of the common themes of research in this field and recall some significant events in its evolution. Finally, we raise

New Tools for Specifying BACnet

March 1, 2002
Author(s)
Steven T. Bushby
The BACnet communication protocol standard makes it possible to integrate a wide variety of building automation and controlproducts. Building owners and the consulting engineering community have had difficulty understanding how to write quality
