181. High Resolution Magnetic Microstructure Imaging Using Secondary Electron Spin Polarization Analysis in a Scanning Electron Microscope
Topic: Nanomagnetics
Published: 8/1/1985
Authors: John Unguris, G Hembree, Robert Celotta, Daniel Thornton Pierce
http://www.nist.gov/manuscript-publication-search.cfm?pub_id=620252

182. Chemisorption Induced Changes in Surface Magnetism and Electronic Structure: Oxygen on Ni(110)
Topic: Nanomagnetics
Published: 1/1/1985
Authors: A Seiler, C Feigerle, J Pena, Robert Celotta, Daniel Thornton Pierce
Abstract: The effect of oxygen chemisorption on the Ni minority-spin 3d holes{long dash}and thus the Ni magnetic moment{long dash}is measured by spin-polarized inverse photoemission. A dramatic reduction of the minority-spin 3d holes is observed, indicating a ...

183. Connection Between Surface Magnetism and Electronic Structure of Oxygen on Ni(110)
Topic: Nanomagnetics
Published: 1/1/1985
Authors: A Seiler, C Feigerle, J Pena, Robert Celotta, Daniel Thornton Pierce
Abstract: The d-band holes which give rise to ferromagnetism in Ni can be directly observed by spin-polarized inverse photoelectron spectroscopy (SPIPES). Only incident electrons polarized in the minority spin direction can fall into unfilled minority spin sta ...

184. Scanning Electron Microscopy with Secondary Electron Spin Polarization Analysis: A New Probe of Magnetic Microstructure
Topic: Nanomagnetics
Published: 1/1/1985
Authors: John Unguris, G Hembree, Daniel Thornton Pierce, Robert Celotta
http://www.nist.gov/manuscript-publication-search.cfm?pub_id=620259

185. Spin Polarization of Secondary Electrons in Transition Metals: Theory
Topic: Nanomagnetics
Published: 1/1/1985
Authors: David R. Penn, S Apell, S Girvin
Abstract: A theory of the spin polarization of the secondary electrons in transition metals and glasses is presented. In contrast to the secondary-electron intensity distribution, the spin polarization is shown to yield useful information about the electron-el ...

186. Theory of Spin Polarized Secondary Electrons in Transition Metals
Topic: Nanomagnetics
Published: 1/1/1985
Authors: David R. Penn, S Apell
Abstract: We show that in contrast to the secondary-electron intensity distribution, the spin polarization, P(E), yields useful information about the electron-electron interaction. The ratio of lifetimes of majority- to minority-spin electrons can be determine ...

188. Spin-Polarized Electron Scattering Studies of the Ferromagnetic Glass, Fe^d81.5^B^d14.5^Si^d4^
Topic: Nanomagnetics
Published: 1/1/1984
Authors: John Unguris, Daniel Thornton Pierce, Robert Celotta
Abstract: Low-energy [(20{math minus}500)-eV] spin-polarized electrons were used to probe the magnetic surface properties of the ferromagnetic metallic glass Fe^d81.5^B^d14.5^Si^d4^. The spin-independent intensity and the spin-dependent asymmetry of the elast ...

190. New Insights from Electron Spin Polarization Studies of Surfaces
Topic: Nanomagnetics
Published: 4/1/1983
Authors: Daniel Thornton Pierce, Robert Celotta
Abstract: Examples of recent investigations in several laboratories, where measurement of effects due to electron spin polarization provided new insight into surface phenomena, will be reviewed. The results to be discussed include the use of spin dependent ele ...
