In　this　paper,　we　investigate　the　well-posedness　and　large　time　behavior　of　solutions　to　the　3D　incompressible　magneto-micropolar　equations.　By　virtue　of　the　(Formula　presented.)　estimate　obtained　through　the　spectral　decomposition　of　the　linearized　magneto-micropolar　equations,　we　show　the　existence　and　uniqueness　of　small　(Formula　presented.)　-strong　solutions　of　the　equations　with　small　initial　data.　Then　basing　on　this　result,　we　derive　sharp　time　decay　estimates　of　the　(Formula　presented.)　-strong　solutions.　©　2023　Informa　UK　Limited,　trading　as　Taylor　&　Francis　Group.
