Abstract：

Sm(Co　balFe　0.09　Cu　0.09Zr　0.03)　7.69　magnet　was　prepared　by　conventional　powder　metallurgy　techniques,　and　the　effect　of　sintering　temperature　on　magnetic　properties　was　studied.　It　is　found　that　with　increasing　sintering　temperature,　the　intrinsic　coercivity　H　cj,　the　remanence　B　r　and　the　maximum　energy　product　(BH)　max　increase　first　and　then　decrease.　The　optimal　magnetic　properties　are　B　r=10.40kGs,　H　cj=25.161kOe,　(BH)　max=25.88MGOe　at　room　temperature　when　the　magnet　is　sintered　at　1230°C.　The　temperature　stability　of　magnets　sintered　at　1230°C　is　excellent　and　can　work　under　the　condition　of　500°C.
