Direct observation of electron confinement in epitaxial graphene nanoislands.
TL;DR: The energy dispersion relation with the quantized electron wave vector obtained from a Fourier analysis of dI/dV maps is established and it is established that the nanoislands preserve the Dirac Fermion properties with a reduced Fermi velocity.

Electric field as a switching tool for magnetic states in atomic-scale nanostructures.
TL;DR: This work proposes a novel route of locally controlling and switching magnetism in low-dimensional atomic-scale magnetic nanostructure exhibiting magnetic bi- or multistability and reveals that externally applied electric field can be used for this purpose.

TL;DR: The elementary surface excitations are studied by spin-polarized electron energy loss spectroscopy on a prototype oxide surface, where the various excitations coexist and the surface phonons and magnons are measured simultaneously and are distinguished based on their different spin nature.
Stress and structure at the NiO/Ag(001) interface
A. Dhaka,Dirk Sander,H. L. Meyerheim,K. Mohseni,E. Soyka,J. Kirschner,Waheed A. Adeagbo,G. Fischer,Arthur Ernst,Wolfram Hergert +9 more
TL;DR: In this article, a combined stress and structural analysis of the growth of epitaxial NiO monolayers on Ag(001) is presented, where a fraction of the first NiO layer is embedded into the Ag surface.
Direct in-depth determination of a complex magnetic configuration in an exchange-coupled bilayer with perpendicular and in-plane anisotropy
Jean-Marc Tonnerre,Marek Przybylski,Marek Przybylski,Mostafa Ragheb,Fikret Yildiz,Hélio C. N. Tolentino,Luc Ortega,J. Kirschner +7 more
TL;DR: In this paper, soft x-ray resonant magnetic reflectivity was used to separate in-and out-of-plane components of a complex magnetic configuration and reveal high sensitivity towards magnetic inhomogeneity, in particular at interfaces.
