We report on the first results of the Noble and Alkali Spin Detectors forUltralight Coherent darK matter (NASDUCK) collaboration. We search for theinteractions of Axion-Like Particles (ALPs) with atomic spins using anearth-based precision quantum detector as it traverses through the galacticdark matter halo. The detector is composed of spin-polarized xenon gas whichcan coherently interact with a background ALP dark matter field and an in-siturubidium Floquet optical-magnetometer. Conducting a five months-long search, wederive new constraints on ALP-proton and ALP-neutron interactions in the$4\times 10^{-15}-4\times 10^{-12}{~\rm eV/c^2}$ mass range. Our limits on theALP-proton (ALP-neutron) couplings improve upon previous terrestrial bounds byup to 3 orders of magnitude for masses above $4\times 10^{-14}{~\rm eV/c^2}$($4\times 10^{-13}{~\rm eV/c^2}$). Moreover, barring the uncertain supernovaconstraints, the ALP-proton bound improves on all existing terrestrial andastrophysical limits, partially closing the unexplored region for couplings inthe range $10^{-6}~{\rm GeV^{-1}}$ to $2\times 10^{-5}~{\rm GeV^{-1}}$.Finally, we also cast bounds on pseudo-scalar dark matter models in which darkmatter is quadratically-coupled to the nucleons.
