1. Absolute Magnetic Moment Measurements of Nickel Spheres
Published: 5/1/2000
Authors: Robert D Shull, Robert D McMichael, L Swartzendruber, Stefan D Leigh
Abstract: The preparation and measurement of nickel spheres for use in the calibration of magnetometers are described. The absolute value of the magnetic moment of a set these spheres near room temperature was measured using the Faraday method. The variation ...

Abstract: 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.

3. Amorphous FeCoCrZrB Ferromagnets for Use as High-Temperature Magnetic Refrigerants
Published: 4/27/2006
Authors: Freemon Johnson, Robert D Shull
Abstract: Magnetic metallic glasses, having large magnetic moments and high Curie Temperatures (TC), have not been widely studied as magnetic refrigerants. In this study, we report on the magnetocaloric effects of five FeCoCrZrB amorphous alloys ((FexCoyCrz)91 ...

4. Anomalous Magnetic Aftereffect of a Frozen Magnetic Fluid
Published: 1/1/2005
Authors: S Taketomi, R V Drew, Robert D Shull
Abstract: A very stably dispersed magnetic fluid (MF) was zero-field-cooled from room temperature of 5 K followed by the application of a magnetic field of 2.86 MA/m for 300 seconds. After the field was removed (t = 0), its residual magnetization M was measur ...

5. Anomalous Switching Behavior of Antiparallel-Coupled CO Layers Separated by a Super-Thin Ru Spacer
Published: 5/1/2002
Authors: V S. Gornakov, Valerian Ivanovich Nikitenko, William F. Egelhoff Jr., Robert D McMichael, Alexander J. Shapiro, Robert D Shull
Abstract: The details of the magnetization reversal mechanisms upon field reversal in coupled ferromagnetic CO (2.5 nm)/Ru(0.5 nm)/Co (2.6 nm) trilayers deposited on obliquely sputtered Ta (10.6 nm) underlayers were studied using the magneto-optical indicator ...

6. Antisymmetric Magnetoresistance in Magnetic Multilayers With Perpendicular Anisotropy
Published: 1/1/2005
Authors: X M Cheng, Sergei Urazhdin, T Tchernyshyov, C L Chien, Valerian Ivanovich Nikitenko, Alexander J. Shapiro, Robert D Shull
Abstract: While magnetoresistance (MR) has generally been found to be symmetric in applied field H in non-magnetic or magnetic metals, we have observed antisymmetric MR in Co/Pt multilayers. Simultaneous domain imaging and transport measurements show that the ...

7. Asymmetrical Domain Nucleation and Unusual Magnetization Reversal of Ultrathin Co Films and Co/Pt Multilayers With Perpendicular Anisotropy
Published: 3/16/2007
Authors: Yu L Iunin, Yury P. Kabanov, Valerian Ivanovich Nikitenko, X M Cheng, Alexander J. Shapiro, Robert D Shull, C L Chien
Abstract: The features of magnetization reversal in Pt/[CO/Pt]_{n}/Pt multilayers (n = 1, 2, 4) have been studied using magneto-optical Kerr microscopy. Asymmetric nucleation centers were revealed where domains form at different positions for up or down magne ...

8. Asymmetry in Elementary Events of Magnetization Reversal in Ferromagnetic/Antiferromagnetic Bilayers
Published: 1/1/2000
Authors: Valerian Ivanovich Nikitenko, V S. Gornakov, Alexander J. Shapiro, Robert D Shull, K Liu, S M Zhou, C L Chien
Abstract: Real-time magneto-optical indicator film images reveal distinct asymmetry in the motion of a single domain wall in a wedged-NiFe/uniform-FeMn bilayer due to the nucleation and behavior of an exchange spring in the antiferromagnetic layer. Magnetizat ...

9. Characterization of Ternary Compounds in the BaO: Fe^d3^: TiO^d2^ System; Ba^d6^Fe^d45^Ti^d17^ O^d106^ and BaRe^d11^Ti^d3^O^d23^
Published: 11/1/1999
Authors: Terrell A Vanderah, W. Wong-Ng, B H. Toby, V. M. Browning, Robert D Shull, Richard G. Geyer, Robert S. Roth

10. Characterization of Ternary Compounds in the BaO:Fe^d2^O^d3^:TiO^d2^ System: Ba^d6^Fe^d45^Ti^d17^O^d106^ and BaFe^d11^Ti^d3^O^d23^
Published: 1/1/1999
Authors: Terrell A Vanderah, Winnie K Wong-Ng, B H. Toby, V. M. Browning, Robert D Shull, Richard G. Geyer, Robert S. Roth
Abstract: Single crystals of Ba^d6^Fe^d45^Ti^d17^O^d106^ and BaFe^d11^Ti^d3^O^d23^ were obtained as major and minor co-products, respectively, by slow-cooling an off-stoichiometric BaO:Fe^d2^O^d3^:TiO^d2^ melt. The former compound exhibits variable stoichiome ...
