Helimagnetic Order in MnSi

Below Tc = 29.5K, MnSi orders magnetically into a rather exotic structure: the magnitude of the local magnetization is constant but its direction is a function of position: there is a constant axial component and a transverse component that spirals about that axis with a long (compared to the lattice spacing) wavelength. Fortunately, µSR can measure the magnitude of the local field regardless of its direction.
