Hidden quantum phase transition in Mn${}_{1-x}$Fe${}_x$Ge: evidence brought by small-angle neutron scattering

E. Altynbaev, S. -A. Siegfried, E. Moskvin +7

The magnetic system of the Mn${}_{1-x}$Fe${}_x$Ge solid solution is ordered in a spiral spin structure in the whole concentration range of $x\in [0÷1]$. The close inspection of the…
