142. 180{degree} Surface Domain Wall Magnetization Profiles: Comparisons Between Scanning Electron Microscopy with Polarization Analysis Measurements, Magneto-Optic Kerr Microscopy Measurements and Micromagnetic Models
Topic: Nanomagnetics
Published: 1/1/1990
Authors: M Scheinfein, P J Ryan, John Unguris, Daniel Thornton Pierce, Robert Celotta
Abstract: We compare measurements of magnetization profiles across a 180{degree} surface domain wall in a 0.24-{mu}m-thick of Permalloy (Ni^d81^Fe^d19^), obtained with scanning electron microscopy with polarization analysis (SEMPA) and longitudinal magneto-opt ...

143. Correlations Between Magnetic Microstructure and Anisotropy with Noise Spectra for CoNi and CoCrTa Thin Film Media
Topic: Nanomagnetics
Published: 1/1/1990
Authors: M Scheinfein, John Unguris, Daniel Thornton Pierce, Robert Celotta
Abstract: This paper reports on two thin film media alloys co^d86^Cr^d12^Ta^d2^ and Co^d75^Ni^d25^ whcih have very different noise characteristics. The magnetic microstructure of thse films was observed with SEMPA. The anisotropy and teh rotational hysteresi ...

144. High Spatial Resolution Quantitative Micromagnetics
Topic: Nanomagnetics
Published: 1/1/1990
Authors: M Scheinfein, John Unguris, Daniel Thornton Pierce, Robert Celotta
Abstract: Magnetization profiles at surfaces are observed with scanning electron microscopy with polarization analysis (SEMPA). This technique allows for quantitative analysis of the vector magnetization profile with 70 nm spatial resolution. Magnetization pr ...

147. Scanning Electron Microscopy with Polarization Analysis (SEMPA): Studies of Surface Magnetic Microstructure
Topic: Nanomagnetics
Published: 1/1/1990
Authors: M W Hart, M Scheinfein, John Unguris, Daniel Thornton Pierce, Robert Celotta
Abstract: SEMPA provides a new and versatile means of imaging surface magnetic microstructure with high resolution. When a ferromagnetic sample is probed by the highly focussed electron beam of an SEM, secondary electrons are generated whose spin polarization ...

150. 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 ...
