Nanoscale imaging of magnetization reversal driven by spin-orbit torque

September 23, 2016
Author(s)
Ian J. Gilbert, Andrew P. Chen, Daniel B. Gopman, Andrew L. Balk, Daniel T. Pierce, Mark D. Stiles, John Unguris
We use scanning electron microscopy with polarization analysis (SEMPA) to image deterministic, spin-orbit torque driven magnetization reversal of in-plane magnetized CoFeB rectangles in zero applied magnetic field. The spin-orbit torque is generated by

Spintronic nanodevices for bioinspired computing

September 20, 2016
Author(s)
Julie Grollier, Damien Querlioz, Mark D. Stiles
The challenge of fabricating bio-inspired hardware is building ultra-high density networks out of complex processing units interlinked by tunable connections. Nanodevices exploiting spin electronics (or spintronics) can be a key technology in this context

Spintronics

September 20, 2016
Author(s)
Hideo Ohno, Mark D. Stiles, Bernard Dieny
Scope: This special issue covers recent developments in spintronics, where the spin degree of freedom of electrons is used to harness otherwise inaccessible capabilities. We have witnessed a wide range of progress, particularly in the past 10 years

Spin Transport at Interfaces with Spin-orbit Coupling: Formalism

September 16, 2016
Author(s)
Vivek P. Amin, Mark D. Stiles
Spin transport remains poorly understood in multilayer systems with interfacial spin-orbit coupling. Currently, drift-diffusion models cannot accurately treat this phenomenon, since the important consequences of interfacial spin-orbit scattering remain

Spin Transport at Interfaces with Spin-Orbit Coupling: Phenomenology

September 16, 2016
Author(s)
Mark D. Stiles, Vivek P. Amin
Spin transport remains poorly understood in multilayer systems with interfacial spin-orbit coupling. While the important consequences of interfacial spin-orbit scattering can be captured by a spin-dependent Boltzmann equation, currently they cannot be

k-asymmetric spin-splitting at the interface between transition metal ferromagnets and heavy metals.

May 23, 2016
Author(s)
Sergiy Grytsyuk, Abderrezak Belabbes, Paul M. Haney, Hyun-Woo Lee, Kyung Jin Lee, Mark D. Stiles, Udo Schwingenschlogl, Aurelien Manchon
We systematically investigate the spin-orbit coupling-induced band splitting originating from inversion symmetry breaking at the interface between a Co monolayer and 4d (Tc, Ru, Rh, Pd, and Ag) or 5d (Re, Os, Ir, Pt, and Au) transition metals. In spite of

Intrinsic Spin Torque Without Spin-Orbit Coupling

December 21, 2015
Author(s)
Kyoung-Whan Kim, Kyung-Jin Lee, Hyun-Woo Lee, Mark D. Stiles
For non-uniform magnetic textures, we derive an intrinsic contribution to the non-adiabatic spin torque that may be the dominant contribution. It differs from previously considered contributions in several ways. It does not depend on the change in

The NIST Plan for Providing Public Access to Results of Federally Funded Research

October 27, 2015

Katherine E. Sharpless, Regina L. Avila, Sally S. Bruce, Wo L. Chang, Robert M. Dimeo, Virginia Covahey, Alan K. Dohne, Heather M. Evans, Aaron P. Fein, Donna J. Kimball, Andrea M. Medina-Smith, Alan E. Munter, James K. Olthoff, Dianne L. Poster, Kathleen M. Roberts, Susannah B. Schiller, John H. Scott, Barbara P. Silcox, James A. St Pierre, Mark D. Stiles
Documentation of the evolution of NIST's plan for providing public access to results of federally funded research is provided, including the plan itself, responses to comments made by NIST staff, and public comments received in response to a request for

Angular dependence of spin-orbit spin-transfer torques

April 6, 2015
Author(s)
Ki-Sueng Lee, Dongwook Go, Aurelien Manchon, Paul M. Haney, Mark D. Stiles, Hyun-Woo Lee, Kyung Jin Lee
In ferromagnet/heavy metal bilayers, an in-plane current gives rise to spin-orbit spin transfer torques. For two-dimensional free-electron and tight-binding models with Rashba spin-orbit coupling, these torques acquire nontrivial dependence on the
