Our search for non-magnetic spin-dependent interactions is based on the measurement of free precession of nuclear spin polarized 3He and 129Xe atoms in a homogeneous magnetic guiding field of about 400 nT. We report on our approach to perform an adiabatic rotation of the guiding field that allows us to modulate possible non-magnetic spin-dependent interactions and to find an optimization procedure for long transverse relaxation times T2* both for Helium and Xenon.
