171. Influence of the Surface on Magnetic Domain Wall Microstructure
Topic: Nanomagnetics
Published: 1/1/1989
Authors: M Scheinfein, John Unguris, Robert Celotta, Daniel Thornton Pierce
Abstract: The magnetization orientations in domain walls at the surfaces of an Fe crystal, a ferromagnetic glass, and a Permalloy film, measured by scanning electron microscopy with polarization analysis, exhibit asymmetric surface N{eacute}el wall profiles wh ...

172. Magnetic Microstructure of Thin Films and Surfaces: Exploiting Spin-polarized Electrons in the SEM and STM
Topic: Nanomagnetics
Published: 1/1/1989
Authors: Daniel Thornton Pierce, M Scheinfein, John Unguris, Robert Celotta
Abstract: Magnetic microstructure, that is the configuration of domains and domain walls in a magnetic material, is of both fundamental interest and of crucial importance for device applications. For example, the ultimate density of magnetic information stora ...

173. Magnetic Microstructure of the (0001) Surface of the HCP Cobalt
Topic: Nanomagnetics
Published: 1/1/1989
Authors: John Unguris, M Scheinfein, Robert Celotta, Daniel Thornton Pierce
Abstract: The magnetic domain structure of the (0001) surface of a hcp cobalt crystal was investigated using scanning electron microscopy with polarization analysis (SEMPA). This is the first observation by SEMPA of both out-of-plane and in-plane magnetization ...

174. Scanning Electron Microscopy with Polarization Analysis Studies of Ni-Fe Magnetic Memory Elements
Topic: Nanomagnetics
Published: 1/1/1989
Authors: John Unguris, M Scheinfein, Robert Celotta, Daniel Thornton Pierce
Abstract: This paper describes the use of Scanning Electron Microscopy with Polarization Analysis to quantitatively image the magnetic structure of permalloy magnetic memory elements. Various methods of determining the absolute magnitude and direction of the ...

177. Domain Images of Ultrathin Fe Films on Ag(100)
Topic: Nanomagnetics
Published: 5/30/1988
Authors: J L Robins, Robert Celotta, John Unguris, Daniel Thornton Pierce, B Jonker, G Prinz
Abstract: Scanning electron microscopy with electron polarization analysis has been used to image domains of ultrathin Fe films grown epitaxially on a Ag(100) substrate. Room-temperature measurements show clearly the existence of large domains of in-plane magn ...

178. Scanning Electron Microscopy with Polarization Analysis: Studies of Magnetic Microstructures
Topic: Nanomagnetics
Published: 5/1/1988
Authors: Robert Celotta, John Unguris, Daniel Thornton Pierce
http://www.nist.gov/manuscript-publication-search.cfm?pub_id=620302

179. Scanning Electron Microscopy with Polarization Analysis (SEMPA): High Spatial Resolution Magnetic Imaging Status Report
Topic: Nanomagnetics
Published: 1/1/1988
Authors: M Scheinfein, John Unguris, Daniel Thornton Pierce, Robert Celotta
Abstract: The scanning electron microscopy with polarization analysis (SEMPA) technique as a means of observing magnetic microstructure is surveyed. A brief description of the technique is given. Particular emphasis is paid to the spin-polarization detector a ...

180. Spin-Polarized Electron Microscopy
Topic: Nanomagnetics
Published: 1/1/1988
Author: Daniel Thornton Pierce
Abstract: A current scientific challenge with many ramifications for magnetic technology is to image magnetic microstructure with the highest possible spatial resolution in order to observe magnetic domains or even spin configurations within a domain wall. Ult ...
