Quantum fluctuations of the spin spiral in Fe-doped MnGe
MnSi and other transition monosilicides, the cubic helimagnets with Dzyaloshinskii-Moriya interaction (DMI) have attracted significant attention during the last time. The magnetic chirality in these systems is determined by the signs of the DM interaction. The helix direction is fixed along the <111> direction by the anisotropic exchange interaction. For MnSi a quantum phase transition (QPT) exhibit under a pressure pc or a critical amount of Mn-atoms substituted by Fe-atoms into the MnSi. The pure MnGe and FeGe are helically ordered but show very different properties. The aim of this proposal is to determine the temperature and magnetic-field evolutions of the magnetic spiral structure for samples Mn1−xFexGe compounds with a Fe-doping around x = 0.4. We plan to study the nature of the spiral fluctuations observed earlier at low (T < 80 K) and high (T > 80 K) temperature ranges. We will also investigate the effect of magnetic field on their size, shape and stability in the magnetic fields (up to 5T).
