摘要

Six different polycrystalline samples of MnSi were produced as a rapidly frozen melt after the single crystal growth in the Czochralski process. With the help of small-angle scattering of polarized neutrons we show that the magnetic spin chirality being scanned along the sample length oscillates strongly on a scale of 23 mm, revealing the volumes of the samples with high degree of an enantiomeric excess. The average chirality of the samples deviates from zero value.
