  We consider the axion-mediated scattering processes between dark matter (DM)
and nucleus. Substantial contributions are made via the CP-odd gluonic current
which induces the spin-dependent process. Since the QCD axion is too feebly
coupled to the visible particles, non-QCD axions are necessary for the current
DM experiments to accomplish the ample sensitivity. In the case of
multi-component DM models, the inelastic scattering processes also make sizable
contributions to the direct detection. The supersymmetry (SUSY) and clockwork
(CW) mechanism provide a realistic model for the QCD and non-QCD axions and the
axion-mediated DM scattering processes. In the SUSY CW axion model, the
lightest axino is the DM particle and the axions mediate the elastic and
inelastic scattering processes. We show that the current and future XENONnT can
produce relevant constraints for some parameter space of the model.
