Papers
Emergent electrodynamics of skyrmions in a chiral magnet
T. Schulz,R. Ritz,Andreas Bauer,M. Halder,Martin Wagner,Christian Franz,Christian Pfleiderer,K. Everschor,Markus Garst,Achim Rosch +9 more
TL;DR: In this article, Hall effect measurements were used to establish quantitatively the predicted emergent electrodynamics of skyrmions in chiral magnets and their depinning from impurities and their subsequent motion.
Formation of a topological non-Fermi liquid in MnSi
TL;DR: A high-pressure study of the metallic state at the border of the skyrmion lattice in MnSi, which represents a new form of magnetic order composed of topologically non-trivial vortices, and suggests empirically that spin correlations with non-Trivial topological character may drive a breakdown of Fermi liquid theory in pure metals.

Observation of two independent skyrmion phases in a chiral magnetic material
A. Chacon,Lukas Heinen,M. Halder,Andreas Bauer,W. Simeth,S. Mühlbauer,Helmuth Berger,Markus Garst,Achim Rosch,Christian Pfleiderer +9 more
TL;DR: In this article, a new skyrmion phase was identified in the chiral magnetic material Cu2OSeO3 at low temperature and in the presence of an applied magnetic field.

Observation of two independent skyrmion phases in a chiral magnetic material
A. Chacon,Lukas Heinen,M. Halder,Andreas Bauer,W. Simeth,S. Mühlbauer,Helmuth Berger,Markus Garst,Achim Rosch,Christian Pfleiderer +9 more
TL;DR: In this paper, the authors reported the identification of a second skyrmion phase in chiral magnet with cubic lattice symmetry, which is thermodynamically disconnected from the well-known, nearly-isotropic, high-temperature phase, and exists only when the external magnetic field is oriented along the crystal axis only.

Symmetry breaking, slow relaxation dynamics, and topological defects at the field-induced helix reorientation in MnSi
Andreas Bauer,A. Chacon,Matthias Wagner,M. Halder,Robert Georgii,Achim Rosch,Christian Pfleiderer,Markus Garst,Markus Garst +8 more
TL;DR: In this article, the Dzyaloshinskii-Moriya interaction in the cubic chiral magnet MnSi stabilizes a magnetic helix -a periodic one-dimensional modulation of the magnetization.
