It is shown that the T − x magnetic phase diagram of Mn1-xFexSi solid solutions exhibits two quantum critical points: x* ~ 0.11, which corresponds to the disappearance of long-range spiral magnetic order, and xc ~ 0.24, which marks the suppression of the phase with short-range magnetic order It is established that the macroscopic reason for observed complicated quantum critical behavior is the evolution of the Fermi-surface driven by an increase of the iron concentration.
