Chiral paramagnetic skyrmion-like phase in MnSi.

ABSTRACT

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}.
