论文摘要
（Mn $ _ {1-X} $ CO $ _X $）的样品具有$ x = 0.15 $和$ x = 0.17 $的样本，其物理特性：磁化和磁化易感性，电阻率和热容量。数据分析还包括$ x = 0.057、0.063、0.09 $的先前结果。带有CO的指示掺杂MNSI完全破坏了螺旋相变的，而基本上可以节省螺旋波动区域，通常位于相变温度的高于相变的温度上。该区域从$ \ sim $ 5到0 k扩散并没有发生太大变化，并形成某种螺旋波动云显示量子关键属性：$ c_p/t \ rightArrow \ rightarrow \ ins t $ t \ rightarrow0 $。
The samples of (Mn$_{1-x}$Co$_x$)Si with $x=0.15$ and $x=0.17$ were grown and their physical properties: magnetization and magnetic susceptibility, resistivity and heat capacity were studied. The data analysis included also the previous results at $x=0.057, 0.063, 0.09$. The indicated doping MnSi with Co completely destroys the helical phase transition whereas basically saves the helical fluctuation area normally situated slightly above the phase transition temperature. This area spreading from $\sim$5 to 0 K is not changed much with doping and forms some sort of helical fluctuation cloud revealing the quantum critical properties: $C_p/T\rightarrow\infty$ at $T\rightarrow0$.
