Abstract
Samples of with and were grown, and their physical properties: magnetization, magnetic susceptibility, resistivity, and heat capacity were studied. The data analysis included previous results at . The doping of MnSi with Co completely destroys the helical phase transition, but it saves the helical fluctuation area normally situated slightly above the phase-transition temperature. This area, spreading from to 0 K does not change much with doping and forms some sort of helical fluctuation cloud, revealing the quantum critical properties: at .
