161. 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 ...

164. 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 ...

165. Surface, Interface and Thin-Film Magnetism
Topic: Nanomagnetics
Published: 1/1/1990
Authors: L Falicov, Daniel Thornton Pierce, S Bader, R Gronsky, K Hathaway, H Hopster, D Lambeth, S Parkin, G Prinz, M Salamon, I Schuller, R Victora
Abstract: A comprehensive review and state of the art in the field of surface, interface, and thin-film magnetism is presented. New growth techniques which produce atomically engineered novel material, special characterization techniques to measure meagnetic p ...

167. 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 ...

168. 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 ...

169. 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 ...
