  "abstract": "We present a detailed investigation of itinerant magnetism in a dipolar Bose gas of chromium atoms confined in a three-dimensional optical lattice, expanding on results recently reported in [1]. In the low-entropy, near-unit filling regime, we employ advanced dynamical decoupling techniques to suppress magnetic-field noise and probe spin coherence across the superfluid-Mott insulator transition. Here, we provide a systematic comparison of different dynamical decoupling sequences, analyze their robustness to experimental imperfections, and quantify their impact on spin dynamics. We also develop perturbative and effective-model approaches that capture the role of both contact and dipolar interactions in determining spin coherence. In the superfluid regime, we discuss a hydrodynamic description that elucidates the emergence and breakdown of metastable ferromagnetism. In the insulating regime, we derive effective spin models including super-exchange terms. In this limit we introduce a tractable spin-1 toy model and a short time expansion of the full spin-3 dynamics that help to shed insight on the interplay between dipolar and contact-driven super-exchange dynamics observed experimentally for spin-3. Our comprehensive analysis bridges experiment and theory, providing new tools and perspectives for understanding itinerant dipolar magnetism in optical lattices.",
