Journal ArticleDOI
Spin-current interaction with a monodomain magnetic body: A model study
TL;DR: In this paper, the authors examined the consequence of spin-current-induced angular momentum deposition in a monodomain Stoner-Wohlfarth magnetic body using the Landau-Lifshitz-Gilbert equation with a phenomenological damping coefficient.
Journal ArticleDOI
Spin torque switching of perpendicular Ta∣CoFeB∣MgO-based magnetic tunnel junctions
D. C. Worledge,Guohan Hu,David W. Abraham,Jonathan Z. Sun,P. L. Trouilloud,Janusz J. Nowak,S. Brown,Michael C. Gaidis,Ewan O'Sullivan,R. P. Robertazzi +9 more
TL;DR: In this paper, the authors investigated spin torque switching in perpendicular magnetic tunnel junctions using Ta∣CoFeB∣MgO free layers and a synthetic antiferromagnet reference layer.
Journal ArticleDOI
Pairing symmetry and flux quantization in a tricrystal superconducting ring of YBa2Cu3O7- delta.
C. C. Tsuei,John R. Kirtley,Cheng-Chung Chi,Lock See Yu-Jahnes,Ayush Gupta,Timothy M. Shaw,Jonathan Z. Sun,Mark B. Ketchen +7 more
TL;DR: Flux quantization in superconducting rings with 0, 2, and 3 grain-boundary Josephson junctions is used to test the pairing symmetry in high-${T}_{c}$ superconductors and results are consistent with $d$-wave pairing symmetry.
Journal ArticleDOI
Measurement of the spin-transfer-torque vector in magnetic tunnel junctions
Jack C. Sankey,Yong-Tao Cui,Jonathan Z. Sun,John C. Slonczewski,Robert A. Buhrman,Daniel C. Ralph +5 more
TL;DR: In this article, the spin angular momentum from a spin-polarized current to a ferromagnet can generate sufficient torque to reorient the magnet's moment, which could enable the development of efficient electrically actuated magnetic memories and nanoscale microwave oscillators.
Journal ArticleDOI
Time-resolved reversal of spin-transfer switching in a nanomagnet.
TL;DR: Time-resolved measurements of spin-transfer-induced (STI) magnetization reversal were made in current-perpendicular spin-valve nanomagnetic junctions subject to a pulsed current bias and demonstrate that spin- transfer induced excitation is responsible for the observed magnetic reversal in these samples.
