• We examine static spin susceptibilities χ_<αβ>(q) of spin components S_α and S_β in the non-centrosymmetric tetragonal system. The anomalous susceptibility, which vanish in centrosymmetric systems, remains showing a momentum dependence like χ_<xx>(q)-χ_<yy>(q)〜q^2_x-q^2_y and χ_<xy>(q)+χ_<yx>(q)〜q_xq_y. A characteristic property of the non-centrosymmetric system is the non-vanishing anomalous susceptibility, whose momentum dependence is not invariant to some symmetry operations of the system. As the direct probe of the anomalous spin susceptibility, we propose a polarized neutron scattering experiment, especially, around an ordering wave vector.
