Specular Electron Scattering in Metallic Thin Films

May 1, 1999
Author(s)
William F. Egelhoff Jr., P J. Chen, Cedric J. Powell, D Parks, F Serpa, Robert McMichael, D Martien, A. E. Berkowitz
Specular electron scattering at the surface of metallic thin films is an important phenomenon for a class of magnetic multilayers known as giant magnetoresistance (GMR) spin valves. In the very best GMR spin valves, a significant part of the GMR effect is

Structural and Magnetic Properties of Electrodeposited Co/Cu Multilayers

March 1, 1999
Author(s)
M Shima, L Salamanca-Riba, Thomas P. Moffat, Robert D. McMichael
A series of [Co(x ML)/Cu(17 ML)]100 multilayers were electrodeposited on Si(0 0 1) substrates covered with Cu seed layers. Magnetic hysteresis loops for lms with x 2 ML have sigmoidal shapes and the temperature dependence indicates a superparamagnetic

Model for Exchange Bias in Polycrystalline Ferromagnet-Antiferromagnet Bilayers

February 1, 1999
Author(s)
Mark D. Stiles, Robert D. McMichael
Polycrystalline ferromagnet-antiferromagnet bilayers exhibit a wide range of interesting magnetic effects. This paper describes a model for these bilayers which explains not only the unidirectional anisotropy that gives rise to the well known shifted

Exchange Bias Relaxation in CoO-Biased Films

January 1, 1999
Author(s)
Robert McMichael, C Lee, Mark D. Stiles, F Serpa, P J. Chen, William F. Egelhoff Jr.
Because the memory of the bias direction is carried by the antiferromagnetic order in exchange biased films, the stability of the antiferromagnetic order is critical to the existence of the exchange bias field. Ferromagnetic resonance was used to measure

Ferromagnetic Resonance Studies of NiO-Coupled Thin Films of Ni 80 Fe 20

October 1, 1998
Author(s)
Robert D. McMichael, Mark D. Stiles, P J. Chen, William F. Egelhoff Jr.
This paper describes ferromagnetic resonance (FMR) and magnetoresistive measurements of thin magnetic films coupled to antiferromagnetic films. First, FMR results for films of Ni 80Fe 20 show that coupling to NiO produces the angular variation in the

Ferromagnetic Resonance Linewidth in Thin Films Coupled to NiO

June 1, 1998
Author(s)
Robert D. McMichael, Mark D. Stiles, P J. Chen, William F. Egelhoff Jr.
The out-of-plane angular dependence of the ferromagnetic resonance linewidth, [Δ] H, has been measured for thin magnetic films coupled to NiO and for uncoupled control films. In the control films, [Δ] is described by nearly angle-independent damping

Optimizing GMR Spin Valves: The Outlook for Improved Properties

June 1, 1998
Author(s)
William F. Egelhoff Jr., P J. Chen, Cedric J. Powell, D Parks, Robert McMichael, J Judy, D Martien, A. E. Berkowitz, J M. Daughton
The current generation of giant magnetoresistance (GMR) spin valves exhibits performance characteristics which are not quite as good as desired for ultrahigh-density nonvolatile memory applications. This paper addresses the scientific issues underlying the

Ferromagnetic Resonance Linewidth in Thin Films Coupled to NiO

January 1, 1998
Author(s)
Robert McMichael, Mark D. Stiles, P J. Chen, William F. Egelhoff Jr.
The out-of-plane angular dependence of the ferromagnetic resonance linewidth, Δ H is described by nearly angle-independent damping parameters. In the NiO-coupled films, however, the damping was found to depend strongly on magnetization orientation, with

Ferromagnetic Resonance Studies of NiO-coupled Thin Films of Ni 80 Fe 20

Author(s)
Robert McMichael, Mark D. Stiles, P J. Chen, William F. Egelhoff Jr.
This paper describes ferromagnetic resonance (FMR) and magnetoresistive measurements of thin magnetic films coupled to antiferromagnetic films. First, FMR results for films of Ni 80Fe^d20 show that coupling to NiO produces the angular variation in the
