171. Spin Nomenclature for Semiconductors and Magnetic Metals
Topic: Nanomagnetics
Published: 6/1/2004
Authors: B Jonker, A Hanbicki, Daniel Thornton Pierce, Mark D Stiles
Abstract: The different conventions used in the semiconductor and magnetic metals communities can cause confusion in the context of spin polarization and transport in simple heterostructures. In semiconductors, terminology is based on the orientation of the ...

172. Spin Polarization in Electron Scattering from Surfaces
Topic: Nanomagnetics
Published: 1/1/1981
Authors: Daniel Thornton Pierce, Robert Celotta

173. Spin Polarization of Injected Electrons
Topic: Nanomagnetics
Published: 5/17/2002
Authors: William F. Egelhoff Jr., Mark D Stiles, David P Pappas, S Alvarado, J Gregg, J Bland, R A. Buhrman, Daniel Thornton Pierce, J Byers, M Johnson, B Jonker
Abstract: A recent paper in Science made the claim of 92% polarization for the injection spin polarized electrons from a Ni scanning tunneling microscopy (STM) tip into GaAs(110). Actually they state their result as 92% efficiency for the injection of 100% imp ...

174. 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 ...

175. Spin Polarized Electron Scattering Studies of Surface Magnetism
Topic: Nanomagnetics
Published: 1/1/1983
Authors: Daniel Thornton Pierce, Robert Celotta, John Unguris

176. Spin Polarized Inverse Photoemission Studies of Surface Magnetism and Electron Structure
Topic: Nanomagnetics
Published: 1/1/1986
Authors: Daniel Thornton Pierce, A Seiler, J Pena, Robert Celotta
Abstract: Spin polarized inverse photoelectron spectroscopy (SPIPES) is shown to be a powerful new technique to study surface and near-surface electronic structure and magnetism. The process, the information obtained, and the apparatus required in a spin pola ...

177. Spin Transfer Torque and Dynamics
Topic: Nanomagnetics
Published: 11/1/2006
Authors: Mark D Stiles, J Miltat
Abstract: The currents in magnetic multilayers are spin polarized and carry enough angular momentum that they can cause magnetic reversal and induce stable precession of the magnetization in thin magnetic layers. The flow of spins is determined by the spin{ma ...

178. Spin Transfer Torque for Continuously Variable Magnetization
Topic: Nanomagnetics
Published: 2/21/2006
Authors: J Xiao, A Zangwill, Mark D Stiles
Abstract: We report quantum and semi-classical calculations of spin current and spin-transfer torque in a free-electron Stoner model for systems where the magnetization varies continuously in one dimension. Analytic results are obtained for an infinite spin sp ...

179. Spin Transfer Torques
Topic: Nanomagnetics
Published: 4/1/2008
Authors: D Ralph, Mark D Stiles
Abstract: This tutorial article is designed for beginning graduate students who are interested in the physics of spin transfer torques in magnetic devices. We provide an elementary discussion of the mechanism of spin transfer torque, and review the theoretical ...

180. Spin Transfer Torques by Point-Contact Spin injection
Topic: Nanomagnetics
Published: 8/24/2009
Authors: Tingyong Chen, Yi Ji, S X Huang, C L Chien, Mark D Stiles
Abstract: Spin-transfer torques (STT) provide a new mechanism to alter the magnetic configuration in magnetic heterostructures, a feat previously only achieved by an external magnetic field. A current flowing perpendicular through a noncollinear magnetic spin ...
