Magnetostriction and angular dependence of FMR linewidth in Tb-doped Ni 0.8 Fe 0.2 thin films

May 15, 2002
Author(s)
Stephen E. Russek, Pavel Kabos, Robert McMichael, C G. Lee, William E. Bailey, R Ewasko, S. Sanders
We present the dependence of the magnetostriction in Ni 0.8Fe 0.2 films on Tb and Gd doping concentration with the measured doping dependence of the high-frequency damping. While the magnetostriction and the high-frequency damping are correlated, the

Ferromagnetic Resonance Mode Interactions in Periodically Perturbed Films

May 1, 2002
Author(s)
Robert McMichael, D J. Twisselmann, John E. Bonevich, P J. Chen, William F. Egelhoff Jr., Stephen E. Russek
rromagnetic resonance linewidth measurements are reported for thin films of Ni 80Fe 20 deposited on substrates with 320 nm period grooves or parallel aperiodic scratches. These films are model systems for studying the effects of inhomogeneity on

Precessional switching in submicrometer spin valves

April 22, 2002
Author(s)
Shehzaad F. Kaka, Stephen E. Russek
Small spin valves are switched using a subnanosecond field pulse applied alongdg the magnetization hard-axis fields increases as the duration is decreased from 325 to 230 ps. This indicates a large-angle precessional motion in response to the transverse

Resonating torque microbalance for in situ measurements of ferromagnetic films

January 1, 2002
Author(s)
John M. Moreland, James A. Beall, Stephen E. Russek
We describe an instrument for in situ monitoring of the magnetic moment of a thin film during deposition with sub-monolayer sensitivity. The instrument measures the magnetic torque on a film as it is being deposited onto a microcantilever excited near its

High Frequency Measurements of CoFeHfO Thin Films

July 1, 2001
Author(s)
Stephen E. Russek, Pavel Kabos, Thomas J. Silva, Fred B. Mancoff, D Wang, Z. T. Qian, J. M. Daughton
High frequency measurements of the transverse susceptibility and damping constant of CoFeHfo thin films have been made over a frequency range of 0.1 GHz to 6 GHz as a function of film resistivity, thickness, and temperature. The films show relatively low

Micromechanical Torque Magnetometer for In Situ Thin-film Measurements

July 1, 2001
Author(s)
John M. Moreland, Albrecht Jander, James A. Beall, Pavel Kabos, Stephen E. Russek
We describe a new type of magnetometer based on a microelectromechanical system (MEMS) for in situ monitoring of magnetic film moment during the film deposition process. The magnetometer measured mechanical torque on a film as it is deposited onto a

Geist, Kalman D. Migler
Abstracts relating to research and development in the NIST Materials Science and Engineering Laboratory (MSEL) are presented for a poster session to be presented to the 2001 MSEL Assessment Panel.

Magnetic Combinatorial Thin-Film Libraries

January 1, 2001
Author(s)
Stephen E. Russek, William E. Bailey, G A. Alers
Magnetic combinatorial libraries have been fabricated to investigate complex magnetic thin-film systems and to provide test systems to develop on-wafer metrologies. The use of combinatorial materials techniques is a new and powerful method to develop and

Current Density Limitations of Spin Valves

September 1, 2000
Author(s)
Stephen E. Russek, Terry J. Gaffron, S. L. Burkett
As spin valve technology evolves, understanding the limitations and design constraints is a critical consideration. Choosing the correct materials combination, aspect ratio and size depends upon careful device characterization. Analysis of spin valves in

Metastable States in Large Angle Magnetization Rotations

September 1, 2000
Author(s)
Pavel Kabos, Shehzaad F. Kaka, Stephen E. Russek, Thomas J. Silva
Large angle rotations were studied in Permalloy thin films and spin valve devices. It is shown that edge effects or inhomogeneities strongly influence the magnetization behavior under certain initial conditions. Complicated intermediate states can form
