Ni–Mn-Ga-Co-Gd　microwires　were　fabricated　by　the　glass-coated　melt　spinning　method,　resulting　in　a　bamboo-grained　structure.　In　this　paper,　the　magnetocaloric　effect　of　Ni–Mn-Ga-Co-Gd　microwires　is　mainly　investigated,　which　is　represented　by　the　isothermal　magnetic　entropy　change　calculated　using　Maxwell　equation.　Specifically,　Ni43Mn30Ga19.9Co7Gd0.1　microwires　exhibit　maximum　entropy　change　of　11.09　J/kg·K　under　5　T　magnetic　field,　which　is　generally　greater　than　that　of　the　current　Ni–Mn-Ga　microwires.　Additionally,　Ni43Mn30Ga19.9Co7Gd0.1　microwires　show　the　temperature　corresponding　to　the　greatest　magnetic　entropy　change　nearer　to　room　temperature　compared　to　other　Ni–Mn-Ga　microwires.　Furthermore,　the　larger　specific　surface　area　of　microwires　will　facilitate　their　application　in　the　field　of　magnetic　refrigeration.　©　2024　Elsevier　Ltd
