MnSi中的手征顺磁类Skyrmion相
A Chiral Paramagnetic Skyrmion-like Phase in MnSi
摘要：
我们提出了一个全面的研究参考helimagnet MnSi的极化中子散射和中子自旋回波光谱，揭示了存在一个完全左手和动态无序相的手征波动。这个阶段可以被确定为一个自发的skyrmion阶段：它出现在一个有限的温度范围内，刚好高于螺旋过渡Tc和共存的螺旋相在Tc。
英文摘要：
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 Tc and coexists with the helical phase at Tc.
