Description:
Author(s): A. Bauer, M. Garst, and C. Pfleiderer Cubic chiral magnets crystallizing in space group P 2 1 3 give rise to a spin structure of nontrivial topology, the so-called skyrmion lattice. The strongly doped semiconductor Fe 1 − x Co x Si is a fascinating member of this material class of compounds as it exhibits helimagnetism over a wide compositional range. The authors study the magnetic properties of this itinerant magnet for different values of x , combine their results with previous reports, and infer the magnetic phase diagrams. The latter are rather isotropic but depend on the field and temperature history. In particular, when cooled in an applied magnetic field, the skyrmion lattice may persist down to lowest temperatures. This history dependence, in combination with the variation of temperature, field, and length scale of the magnetic order by means of compositional tuning, makes Fe 1 − x Co x Si an excellent material for future experiments studying skyrmions.
