Observation of two independent skyrmion phases in a chiral magnetic material
A. Chacon, L. Heinen, M. Halder +7
Magnetic materials can host skyrmions, which are topologically non-trivial spin textures. In chiral magnets with cubic lattice symmetry, all previously-observed skyrmion phases req…
Thermodynamic evidence of a second skyrmion lattice phase and tilted conical phase in Cu0SeO
M. Halder, A. Chacon, A. Bauer +7
Precision measurements of the magnetization and ac susceptibility of Cu0SeO are reported for magnetic fields along different crystallographic directions, focussing on the b…
Reciprocal space mapping of magnetic order in thick epitaxial MnSi films
B. Wiedemann, A. Chacon, S. L. Zhang +9
We report grazing incidence small angle neutron scattering (GISANS) and complementary off-specular neutron reflectometry (OSR) of the magnetic order in a single-crystalline epitaxi…
Symmetry breaking, slow relaxation dynamics, and topological defects at the field-induced helix reorientation in MnSi
A. Bauer, A. Chacon, M. Wagner +4
We report a study of the reorientation of the helimagnetic order in the archetypal cubic chiral magnet MnSi as a function of magnetic field direction. The reorientation process as…
Formation of a topological non-Fermi liquid in MnSi
R. Ritz, M. Halder, M. Wagner +3
Fermi liquid theory provides a remarkably powerful framework for the description of the conduction electrons in metals and their ordering phenomena, such as superconductivity, ferr…
Giant generic topological Hall resistivity of MnSi under pressure
R. Ritz, M. Halder, C. Franz +5
We report detailed low temperature magnetotransport and magnetization measurements in MnSi under pressures up to . Tracking the role of sample quality, pressure…
