Journal ArticleDOI
Spontaneous atomic-scale magnetic skyrmion lattice in two dimensions
Stefan Heinze,Kirsten von Bergmann,Matthias Menzel,Jens Brede,André Kubetzka,Roland Wiesendanger,Gustav Bihlmayer,Stefan Blügel +7 more
TL;DR: In this article, a two-dimensional square lattice of skyrmions on the atomic length scale was described as the magnetic ground state of a hexagonal Fe film of one-atomic-layer thickness on the Ir(111) surface.
Journal ArticleDOI
Writing and deleting single magnetic skyrmions.
Niklas Romming,Christian Hanneken,Matthias Menzel,Jessica Bickel,Boris Wolter,Kirsten von Bergmann,André Kubetzka,Roland Wiesendanger +7 more
TL;DR: This work reports on an ultrathin magnetic film in which individual skyrmions can be written and deleted in a controlled fashion with local spin-polarized currents from a scanning tunneling microscope, demonstrating the feasibility of using spin- polarized tunnel currents for the controlled manipulation of individual sk Kyrmions.
MonographDOI
Scanning probe microscopy and spectroscopy : methods and applications
TL;DR: In this article, the authors provide a clear and comprehensive introduction to scanning tunnelling microscopy and related scanning probe techniques, including the design and instrumentation of practical STM and associated systems, as well as applications in condensed matter physics, chemistry, biology, and nanotechnology.
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
Chiral magnetic order at surfaces driven by inversion asymmetry
Matthias Bode,Matthias Bode,Marcus Heide,K. von Bergmann,P. Ferriani,Stefan Heinze,Gustav Bihlmayer,André Kubetzka,O. Pietzsch,Stefan Blügel,Roland Wiesendanger +10 more
TL;DR: In this article, the Dzyaloshinskii-Moriya interaction was shown to lead to a left-rotating spin cycloid in a single atomic layer of manganese on a tungsten substrate.
