Journal ArticleDOI
Crystal Handedness and Spin Helix Chirality in Fe 1-x Co x Si
S. V. Grigoriev,Dmitry Chernyshov,Vadim Dyadkin,Vladimir Dmitriev,S. V. Maleyev,E. V. Moskvin,Dirk Menzel,J. Schoenes,Helmut Eckerlebe +8 more
TL;DR: It is shown, with the help of polarized neutrons, that the cubic magnets Fe1-xCoxSi with Dzyaloshinskii-Moriya interaction can be switched between left and right chiral states of the spin helix.
Journal ArticleDOI
Spin-echo small angle neutron scattering in Delft
TL;DR: In this paper, the authors describe two spin-echo instruments for neutron small angle scattering, which have been installed at the reactor institute in Delft, and compare them with magnetized foils and resonant spin flippers.
Journal ArticleDOI
Magnetic structure of MnSi under an applied field probed by polarized small-angle neutron scattering
S. V. Grigoriev,S. V. Maleyev,A. I. Okorokov,Yu. O. Chetverikov,Peter Böni,Robert Georgii,D. Lamago,Helmut Eckerlebe,K. Pranzas +8 more
TL;DR: The magnetic structure of a single crystal MnSi under applied magnetic field has been studied by small angle diffraction with polarized neutrons below 28.7°C and has been shown that in zero field the spin structure of MnSi consists of four left-handed spiral domains oriented along four ⟨111⟩ axes as discussed by the authors.
Journal ArticleDOI
Magnetic structure of Fe 1 − x Co x Si in a magnetic field studied via small-angle polarized neutron diffraction
S. V. Grigoriev,Vadim Dyadkin,Dirk Menzel,J. Schoenes,Yu. O. Chetverikov,A. I. Okorokov,Helmut Eckerlebe,S. V. Maleyev +7 more
TL;DR: In this article, the magnetic properties of cubic magnet with Dzyaloshinskii-Moriya (DM) interaction were investigated and it was shown that the same set of parameters governed the magnetic susceptibility of these compounds.
Journal ArticleDOI
Field-induced reorientation of the spin helix in MnSi near T c
TL;DR: In this article, a weak magnetic field applied along one of the axes produces a single domain sample with the helix wave vector along the field and the 90 degree sign reorientation of the spin spiral from the [111] axis to [110] axis is observed in the field range from 130 to 180 mT in the close vicinity to T{sub c}.
