Cubic magnetic anisotropy in 20 magnets: Interplay of anisotropy and magnetic order in FeCoSi
G. Gödecke, A. O. Leonov, J. Grefe +2
The metallic systems MnSi and FeCoSi are known to feature a generic magnetic phase diagram primarily determined by the isotropic exchange and Dzyaloshinskii-Moriya in…

Low-Temperature Skyrmions and Spiral Reorientation Processes in Chiral Magnets with Cubic Anisotropy: Guidelines for Bridging Theory and Experiment
A. O. Leonov, G. Gödecke, J. Grefe +2
We revisit the phenomenological Dzyaloshinskii framework, a central theoretical approach for describing magnetization processes in bulk chiral magnets, and demonstrate how magnetoc…

Near coincidence of metal-insulator transition and quantum critical fluctuations: Electronic ground state and magnetic order in FeCoSi
J. Grefe, P. Herre, Y. Hilgers +7
We present a detailed study of the electronic and magnetic ground state properties of FeCoSi using a combination of macroscopic and microscopic experimental technique…
