István Kézsmárki,István Kézsmárki,Sándor Bordács,Peter Milde,Erik Neuber,Lukas M. Eng,Jonathan S. White,Henrik M. Rønnow,Charles Dewhurst,Masahito Mochizuki,Masahito Mochizuki,K. Yanai,Hiroyuki Nakamura,D. Ehlers,Vladimir Tsurkan,Vladimir Tsurkan,Alois Loidl +16 more
TL;DR: A new Néel-type of SkL describable as a superposition of spin cycloids in contrast to the Bloch-type SkL in chiral magnets described in terms of spin helices is found in the polar magnetic semiconductor GaV4S8 with rhombohedral (C3v) symmetry and easy axis anisotropy.
Journal ArticleDOI
Unwinding of a skyrmion lattice by magnetic monopoles.

TL;DR: This study revealed that skyrmions vanish by a coalescence, forming elongated structures, and numerical simulations showed that changes of topology are controlled by singular magnetic point defects.
Journal ArticleDOI
Accuracy and resolution limits of Kelvin probe force microscopy
TL;DR: In this paper, a detailed experimental and theoretical study of the accuracy and resolution provided by the two methods, including the setup for the frequency-modulation technique, is presented, and the experimental results are compared with the predictions of a numerical simulation based on a realistic model for the tip-sample geometry.
Journal ArticleDOI
Stimulated emission of surface plasmons at the interface between a silver film and an optically pumped dye solution.
TL;DR: Amplification of SPs by stimulated emission is demonstrated, which can be considered analogous to photon amplification in a laser, thereby suggesting novel approaches in the field of nano-optics.
Journal ArticleDOI
The route to functional graphene oxide.
Kinga Haubner,Jan Murawski,Phillip Olk,Lukas M. Eng,Christoph Ziegler,B. Adolphi,Evelin Jaehne +6 more
TL;DR: An easy-to-use, successful, and reproducible route to synthesize functionalized graphite oxide (GO) and its conversion to graphene-like materials through chemical or thermal reduction of GO is reported.
