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.
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.
Journal ArticleDOI
Field-dependent size and shape of single magnetic Skyrmions.
TL;DR: The atomic-scale spin structure of individual isolated Skyrmions in an ultrathin film is investigated in real space by spin-polarized scanning tunneling microscopy and an analytical expression is proposed and applied to connect the experimental data to the original theoretical model describing chiral SkyrMions.
Journal ArticleDOI
Electric-field-driven switching of individual magnetic skyrmions
Pin-Jui Hsu,André Kubetzka,Aurore Finco,Niklas Romming,Kirsten von Bergmann,Roland Wiesendanger +5 more
TL;DR: In this paper, the direction of the electric field generated by the tip of a scanning tunnelling microscope can be exploited to locally and reversibly switch between a ferromagnetic state and a skyrmion.
