The　stability　and　large-time　behavior　problem　on　the　magneto-micropolar　equations　has　evoked　a　considerable　interest　in　recent　years.　In　this　paper,　we　study　the　stability　and　exponential　decay　near　magnetic　hydrostatic　equilibrium　to　the　two-dimensional　magneto-micropolar　equations　with　partial　dissipation　in　the　domain　(Formula　presented.).　In　particular,　we　takes　advantage　of　the　geometry　of　the　domain　(Formula　presented.)　to　divide　u　into　zeroth　mode　and　the　nonzero　modes,　and　obey　a　strong　version　of　the　Poincaré＇s　inequality,　which　plays　a　crucial　role　in　controlling　the　nonlinearity.　Moreover,　we　find　that　the　oscillation　part　of　the　solution　decays　exponentially　to　zero.　Finally,　our　result　mathematically　verifies　that　the　stabilization　effect　of　a　background　magnetic　field　on　magneto-micropolar　fluids.　©　2023　Informa　UK　Limited,　trading　as　Taylor　&　Francis　Group.
