We present a comprehensive study of chiral fluctuations in the reference helimagnet MnSi by polarized neutron scattering and neutron spin echo spectroscopy, which reveals the existence of a completely left-handed and dynamically disordered phase. This phase may be identified as a spontaneous Skyrmion phase: it appears in a limited temperature range just above the helical transition T_{C} and coexists with the helical phase at T_{C}.
我们通过极化中子散射和中子自旋回波光谱对参考螺旋磁体MnSi中的手征涨落进行了全面研究，结果揭示了一个完全左旋且动态无序相的存在。这个相可能被认定为自发斯格明子相：它出现在略高于螺旋转变温度(T_{C})的有限温度范围内，并在(T_{C})时与螺旋相共存。
