We control the spin precession in the quantum Hall edge states by combining the adiabatic and non-adiabatic process and detected the spin-precession via conductance. We expected that the signal is the largest at the filling factor 2. However the result shows that the signal become larger with increasing the filling factor. This indicate that the precession is dependent on the overlap of the wave functions in different channels.
