141. Effects of Interfacial Roughness on the Magnetoresistance of Magnetic Metallic Multilayers
Topic: Nanomagnetics
Published: 1/1/1994
Authors: R Hood, L Falicov, David R. Penn
Abstract: The Boltzmann equation is solved for a system consisting of a ferromagnetic-normal-metallic multilayer. The in-plane magnetoresistance of Fe/Cr and Fe/Cu superlattices is calculated for (1) varying interfacial geometric random roughness with no late ...

142. Hot Electron Spin-Valve Effect in Coupled Magnetic Layers
Topic: Nanomagnetics
Published: 1/1/1994
Authors: Robert Celotta, John Unguris, Daniel Thornton Pierce
Abstract: SEMPA observations of magnetic exchange coupling in the Fe/Ag/Fe, Fe/Au/Fe, and Fe/Cr/Fe systems reveal an intensity variation in the emitted secondary electron signal that depends only on whether the Fe layers are coupled in a ferromagnetic or antif ...

143. Influence of Cr Growth on Exchange Coupling in Fe/Cr/Fe(100)
Topic: Nanomagnetics
Published: 1/1/1994
Authors: Daniel Thornton Pierce, Joseph A Stroscio, John Unguris, Robert Celotta
Abstract: Scanning electron microscopy with polarization-analysis (SEMPA) measurements of the dependence of the oscillations of the exchange coupling in Fe/Cr/Fe(100) structures on the Cr growth temperature are correlated with the thickness fluctuations in Cr ...

144. Investigation of Exchange Coupled Magnetic Layers by Scanning Electron Microscopy with Polarization Analysis (SEMPA)
Topic: Nanomagnetics
Published: 1/1/1994
Authors: Daniel Thornton Pierce, John Unguris, Robert Celotta
http://www.nist.gov/manuscript-publication-search.cfm?pub_id=620415

145. Oscillatory Exchange Coupling in Fe/Au/Fe(100)
Topic: Nanomagnetics
Published: 1/1/1994
Authors: John Unguris, Robert Celotta, Daniel Thornton Pierce
Abstract: Scanning electron microscopy with polarization analysis was used to investigate the interlayer exchange coupling in Fe/Au/Fe(100) sandwich structures. The films were epitaxially grown on single-crystal Fe(100) substrates. Electron diffraction measure ...

146. Exchange Coupling in Magnetic Heterostructures
Topic: Nanomagnetics
Published: 1/1/1993
Author: Mark D Stiles
Abstract: Many structures consisting of magnetic layers separated by a nonmagnetic spacer layer show an oscillatory exchange coupling. This behavior is explained in terms of a simple model that shows that the Fermi surface of the spacer layer material is resp ...

147. Magnetic Moments in Cr Thin Films on Fe(100)
Topic: Nanomagnetics
Published: 1/1/1993
Authors: Daniel Thornton Pierce, Robert Celotta, John Unguris
Abstract: The magnetism at the surface of a Cr film grown epitaxially on a Fe(100) whisker is observed as a function of Cr thickness by scanning electron microscopy with polarization analysis. Use of a wedge-shaped film of linearly increasing thickness allows ...

148. Oscillatory Magnetic Coupling in Fe/Ag/Fe(100) Sandwich Structures
Topic: Nanomagnetics
Published: 1/1/1993
Authors: John Unguris, Robert Celotta, Daniel Thornton Pierce

149. Magnetism in Cr Thin Films on Fe(100)
Topic: Nanomagnetics
Published: 1/1/1992
Authors: John Unguris, Robert Celotta, Daniel Thornton Pierce
Abstract: The spin polarization of secondary electrons from a Cr film on Fe(100), measured with scanning electron microscopy with polarization analysis, oscillates as a function of Cr thickness with a period near two atomic layers, consistent with incommensura ...

150. Correlations of Modulation Noise with Magnetic Microstructure and Intergranular Interactions for CoCrTa and CoNi Thin Film Media
Topic: Nanomagnetics
Published: 1/1/1991
Authors: Mahbub R. Khan, S Y. Lee, S L Duan, J L Pressesky, Neil Heiman, D E Speliotis, M Scheinfein
Abstract: This paper reports on two thin-film media alloys Co^d86^Cr^d12^Ta^d2^ and Co^d75^Ni^d25^ which have very different noise characteristics. The magnetic microstructure of these films was observed with scanning electron microscopy with polarization anal ...
