Journal ArticleDOI
Direct Observation of Internal Spin Structure of Magnetic Vortex Cores
TL;DR: The results confirm theoretical predictions that the size and the shape of the vortex core as well as its magnetic field dependence are governed by only two material parameters, the exchange stiffness and the saturation magnetization that determines the stray field energy.
Journal ArticleDOI
Left atrial appendage closure with the Watchman device in patients with a contraindication for oral anticoagulation: the ASAP study (ASA Plavix Feasibility Study With Watchman Left Atrial Appendage Closure Technology).

TL;DR: In this article, the safety and efficacy of left atrial appendage closure with the Watchman device was evaluated in nonvalvular atrial fibrillation (AF) patients ineligible for warfarin therapy.
Journal ArticleDOI
Realizing all-spin-based logic operations atom by atom.
TL;DR: This work combined bottom-up atomic fabrication with spin-resolved scanning tunneling microscopy to construct and read out atomic-scale model systems performing logic operations, using substrate-mediated indirect exchange coupling to achieve logical interconnection between individual atomic spins.
Journal ArticleDOI
Revealing magnetic interactions from single-atom magnetization curves.
TL;DR: The ability to measure magnetization curves of individual magnetic atoms adsorbed on a nonmagnetic metallic substrate with use of a scanning tunneling microscope with a spin-polarized tip and map out low-energy magnetic interactions on the atomic scale is demonstrated.
Journal ArticleDOI
Atom-by-atom engineering and magnetometry of tailored nanomagnets
Alexander A. Khajetoorians,Jens Wiebe,Bruno Chilian,Samir Lounis,Stefan Blügel,Roland Wiesendanger +5 more
TL;DR: In this paper, small clusters of magnetic atoms can behave in very different ways to those same atoms in bulk, and they can be arranged one by one into complex but well-defined patterns on a copper surface.
