The　addition　of　iron　content　in　Sm-Co　magnets　is　beneficial　for　both　the　improvement　of　magnetic　properties　and　the　reduction　of　raw　material　costs.　However,　studies　on　Fe-rich　Sm(CoFeCuZr)z　magnets　show　that　Cu-lean　phenomenon　at　grain　boundaries　leads　to　the　decrease　of　coercivity　and　squareness.　In　order　to　improve　the　element　distribution,　adding　Sm71Cu29　low　melting　point　eutectic　alloy　is　an　effective　method.　The　results　show　that　it　can　improve　the　Cu-lean　phenomenon　at　grain　boundaries,　and　it　makes　the　distribution　of　elements　near　the　grain　boundaries　more　uniform.　When　the　addition　amount　reaches　0.5　wt%,　the　micro-scale　element　distribution　of　the　magnet　is　improved,　which　in　turn　leads　to　a　wider　cell　boundary　phase　and　larger　values　of　domain-wall　energy　differences　in　the　nanoscale　cellular　structure.　MOKE　microscopy　finds　that　the　Sm71Cu29-added　magnets　at　the　thermal　demagnetization　state　have　finer　magnetic　domains,　and　the　grain　boundaries　of　Sm71Cu29-added　magnets　have　stronger　pinning　ability　during　the　demagnetization　process,　contributing　to　high　coercivity.　The　magnet　has　high　comprehensive　magnetic　properties　when　adding　0.5　wt%:　Br　=　12.02　kG,　Hcj　=　21.69　kOe,　(BH)max　=　33.05　MGOe.　©　2024　Elsevier　B.V.
