Real-Space and Reciprocal-Space Berry Phases in the Hall Effect of Mn${}_{1-\mathrm{x}}$Fe${}_{\mathrm{x}}$Si

C. Franz, F. Freimuth, A. Bauer +8

We report an experimental and computational study of the Hall effect in Mn${}_{1-\mathrm{x}}$Fe${}_{\mathrm{x}}$Si, as complemented by measurements in Mn${}_{1-\mathrm{x}}$Co${}_{\mathrm{x}}$Si, when helimagn…
