We are concerned with magneto-micropolar fluid equations (1.3)–(1.4). The global existence of solutions to the Cauchy problem is investigated under certain conditions. Precisely, for the magneto-micropolar-Navier–Stokes (MMNS) system, we obtain global existence and large time behavior of solutions near a constant states in R 3. Appealing to a refined pure energy method, we first obtain a global existence theorem by assuming that the H 3 norm of the initial data is small, but the higher order derivatives can be arbitrary large. If the initial data belongs to homogeneous Sobolev norms H˙− s (0≤ s< 3 2) or homogeneous Besov norms B˙ 2,∞− s (0< s≤ 3 2), we obtain the optimal decay rates of the solutions and its higher order derivatives. As an immediate byproduct, we also obtain the usual L p− L 2 (1≤ p≤ 2) type of the decay rates without requiring that the L p norm of initial data is small. At last, we derive a weak solution to (1.3)–(1.4) in R 2 with large initial data.
