In recent years complex forms of magnetic order based on spin chirality in non-centrosymmetric systems has attracted great interest in condensed matter physics. Among many systems, MnSi is ideally suited to study the properties of unconventional magnetic states. With the proposed experiment we would like to extend our studies to Mn(1-x)Fe(x)Si, close to the quantum critical point, where the magnetic phase transition is suppressed to zero temperature. The high resolution neutron spin echo and polarization analysis capabilities of IN11 will allow us to investigate the interplay between the quantum critical point and the chiral fluctuations to establish the generality of the precursor phenomena and the effect of disorder on the helical magnetic order.
