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

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) 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

Reference Model for Electric Vehicle Battery Recovery in a Circular Economy

September 30, 2025
Author(s)
Matthew Triebe, Nehika Mathur, Ashley Hartwell, Katherine Morris
Electric vehicle batteries, which use a significant amount of critical materials, have the potential to be a reliable secondary source of those high-value materials at the end of their life to meet future needs. In this paper we present a reference model

Bilateral NMI Comparison of Guarded-Hot-Plate Apparatus

April 27, 2014
Author(s)
Alain Koenen, Robert R. Zarr, William F. Guthrie
Two national metrology laboratories (NMI) have conducted an international interlaboratory comparison on thermal conductivity on two thermal insulation reference materials. The Laboratoire national de métrologie et d'Essais (LNE) from France and the

OpenADR Advances

November 1, 2012

The Effect of Stress Induced Anisotropy in Patterned FeCo Thin Film Structures

April 1, 2006
Author(s)
Wonpil Yu, J A. Bain, Willard C. Uhlig, John Unguris
The usage of high moment FeCo alloys in magnetic recording heads can result in stress induced anisotropy due to the high magnetostriction constants of FeCo alloys with 30% to 50% Co. In this work, 1um thick FeCo (65% Fe, 35% Co) sheet films with a Cu
