Title:
Magnetic Field Dependence of Chiral Fluctuations in {{MnSi}}
Abstract:
Polarized neutrons were used to determine the antisymmetric part of the magnetic dynamical susceptibility w\dh{}Q; o\TH{} in the weak ferromagnet MnSi. We find that above the Curie temperature Tc the spin fluctuations are incommensurate with the chemical lattice and that w\dh{}Q; o\TH{} depends on the polarization of the incident neutron beam Pi like \dh{}Q Á Pi\TH{} where Q is the scattering vector. Because the crystal structure of MnSi is non-centrosymmetric we interpret these results in te...    »
