    Magnetic fluctuations and correlations in MnSi: Evidence for a chiral skyrmion spin liquid phase
    (American Physical Society, 2011-06-20) Pappas, C; Lelièvre-Berna, E; Bentley, PM; Falus, P; Fouquet, P; Farago, B
    We present a comprehensive analysis of high-resolution neutron scattering data involving neutron spin echo spectroscopy and spherical polarimetry, which confirm the first-order nature of the helical transition in MnSi. The experiments reveal the existence of a totally chiral dynamic phase in a very narrow temperature range above T-C. This unconventional magnetic short-range order has a topology similar to that of a skyrmion liquid or the blue phases of liquid crystals. © 2011, American Chemical Society.
