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.
