Abstract: We report on the search for a new spin--dependent interaction $\vec{\sigma}\cdot \hat{r}$ which causes a shift in the precession frequency of nuclear spin polarized gases. Therefore we use a comagnetometer that is based on the detection of freely precessing nuclear spins from $^{3}$He and $^{129}$Xe gas samples using SQUIDs as low-noise magnetic flux detectors. As result we could improve the upper bounds of the dimensionless product $g_{s}g_{p}$ of the monopole-dipole coupling of an axion to the spin of a bound neutron in the mass range between $2\:\mu$eV and $500\:\mu$eV (corresponding to force ranges between $3\cdot 10^{-4}\:\textrm{m}$ and $10^{-1}\:\textrm{m}$) by up to 4 orders of magnitude.
