Journal ArticleDOI
Skyrmion Lattice in a Chiral Magnet
Sebastian Mühlbauer,B. Binz,F. Jonietz,Christian Pfleiderer,Achim Rosch,A. Neubauer,Robert Georgii,Peter Böni +7 more
TL;DR: This study experimentally establishes magnetic materials lacking inversion symmetry as an arena for new forms of crystalline order composed of topologically stable spin states in the chiral itinerant-electron magnet MnSi.
Journal ArticleDOI
Fermi-liquid instabilities at magnetic quantum phase transitions
TL;DR: In this article, the authors discuss the instabilities of the Fermi-liquid state of conduction electrons in metals with particular emphasis on magnetic quantum critical points, with the aim of assessing the validity of presently available theory.
Journal ArticleDOI
Topological Hall Effect in the A Phase of MnSi
TL;DR: This work reports a distinct additional contribution to the Hall effect in the temperature and magnetic field range of the proposed Skyrmion lattice, where such a contribution is neither seen nor expected for a normal helical state.
Journal ArticleDOI
Spin Transfer Torques in MnSi at Ultralow Current Densities
F. Jonietz,Sebastian Mühlbauer,Christian Pfleiderer,A. Neubauer,W. Münzer,Andreas Bauer,T. Adams,Robert Georgii,Peter Böni,Rembert A. Duine,K. Everschor,Markus Garst,Achim Rosch +12 more
TL;DR: Spin Control Controlling and manipulating the spin of an electron is a central requirement for applications in spintronics and an efficient and simple superconducting-based single-electron transistor that can produce spin current with controlled flow is designed and fabricated.
Journal ArticleDOI
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.
