Abstract:
We report the transverse magnetoresistance $̊ho$xx and Hall effect $̊ho$xy in MnSi between room temperature and 2.5K for magnetic field up to 9T. Magnetic field suppresses the resistivity at all temperatures and fields, characteristic of scattering by an abundance of soft magnetic fluctuations that are quenched by magnetic field. Anomalous contributions to the Hall effect for temperatures below the onset of helimagnetic order, T
