191. 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 ...

192. Spin-Polarized Electrons
Topic: Nanomagnetics
Published: 1/1/2001
Authors: Daniel Thornton Pierce, Robert Celotta
Abstract: The electron-sodium system is an excellent prototype of non-relativistic electron scattering from a quasi-one-electron atomic target, and is tractable both experimentally and theoretically. Recently, this system has been studied in a series of sophi ...

193. Spin-Polarized Inverse Photoelectron Spectroscopy of Solid Surfaces: Ni(110)
Topic: Nanomagnetics
Published: 10/4/1982
Authors: John Unguris, A Seiler, Robert Celotta, Daniel Thornton Pierce, Philip Johnson, N. Smith
Abstract: Inverse photoemission spectra have been measured on Ni(110) at 9.7-eV photon energy with a spin-polarized electron source. Consistent with band theory, a d-band-derived peak is observed just above the Fermi level that corresponds to transitions to mi ...

194. Spin-Wave Propagation in the Presence of Interfacial Dzyaloshinskii-Moriya Interaction
Topic: Nanomagnetics
Published: 11/4/2013
Authors: Jung-Hwan Moon, Soo-Man Seo, Kyung Jin Lee, Kyoung-Whan Kim, Jisu Ryu, Hyun-Woo Lee, Robert D McMichael, Mark D Stiles
Abstract: In ferromagnetic thin films, broken inversion symmetry and spin-orbit coupling give rise to interfacial Dzyaloshinskii-Moriya interactions. Analytic expressions for spin-wave properties show that the Dzyaloshinskii-Moriya interaction leads to non-re ...

195. Spin-resolved Inverse-Photoemission Study of Ni(001) and its Chemisorption
Topic: Nanomagnetics
Published: 11/15/1987
Authors: L Klebanoff, Ronald K. Jones, Daniel Thornton Pierce, Robert Celotta

196. Structural Phase Transitions on Nickel at the Curie Temperature
Topic: Nanomagnetics
Published: 3/16/1981
Authors: J Hamilton, Terrence J Jach
Abstract: It is observed that a reversible step period rearrangement on clean nickel single-crystal surfaces occurs in the immediate vicinity of the Curie temperature. Reversible carbon segregation is observed on the same crystal surfaces below the Curie poin ...

197. Suppression of Orange-Peel Coupling in Magnetic Tunnel Junctions by Preoxidation
Topic: Nanomagnetics
Published: 4/17/2006
Authors: William F. Egelhoff Jr., Robert D McMichael, Cindi L Dennis, Mark D Stiles, Alexander J. Shapiro, Brian B. Maranville, Cedric John Powell
Abstract: We have found that preoxidation of the bottom Co electrode in magnetic tunnel junctions (MTJs) very effectively suppresses orange-peel coupling. The result is a free layer that is much softer. Work by others has demonstrated that preoxidation is com ...

198. Surface Magnetic Microstructural Analysis Using Scanning Electron Microscopy with Polarization Analysis (SEMPA)
Topic: Nanomagnetics
Published: 1/1/1990
Authors: M Scheinfein, John Unguris, Daniel Thornton Pierce, Robert Celotta

199. Surface Magnetic Microstructure
Topic: Nanomagnetics
Published: 1/1/1990
Authors: M Scheinfein, John Unguris, Robert Celotta, Daniel Thornton Pierce
Abstract: The way in which a magnetic solid minimizes its energy through the formation of domains and domain walls is strongly influenced by the presence of the surface. At the surface, a bulk Blich wall may change into a Neel wall in order to reduce the magn ...

200. Surface Magnetic Properties of Amorphous Ferromagnets Studied Using Electron Spin Polarization
Topic: Nanomagnetics
Published: 1/1/1983
Authors: Daniel Thornton Pierce, Robert Celotta, John Unguris, H Siegmann
