Supporting density functional theory (DFT) calculations allow the determination of a single muon stopping site whose magnetic environment is consistent with the proposed ground-state magnetic structure. $\\mu^{+}$SR measurements of the dynamics reveal behavior consistent with spin-wave excitations below $T_{\\mathrm{N2}}$.
