Anisotropic　hybrid　bulk　magnets　of　MnBi/NdFeB　with　different　composition　ratio　have　been　prepared　with　starting　MnBi　and　Nd2Fe14B　powders　as　well　as　epoxy　resin　as　a　binder　in　case　it　is　needed　to　form　bulk　samples.　It　has　been　found　that　the　ratio　between　the　two　phases　in　content　has　a　remarkable　influence　on　the　magnetic　properties,　the　thermal　stability　and　the　density　of　the　bulk　magnets.　With　increasing　MnBi　content　the　binder　addition　can　be　reduced.　When　the　MnBi　content　is　larger　than　30　wt%,　no　binder　is　needed.　On　the　other　hand,　the　coercivity　and　saturation　magnetization　were　increased　significantly　with　increasing　NdFeB　content.　When　the　NdFeB　content　was　increased　from　0%　to　50%,　the　maximum　energy　product　was　enhanced　from　4.7　to　10.0　MGOe,　respectively.　The　energy　product　then　decreased　gradually　with　the　NdFeB　content　due　to　the　reduced　density　of　the　hybrid　magnet.　The　thermal　stability　measurements　showed　that　the　temperature　coefficient　of　coercivity　grew　with　the　MnBi　content　and　became　positive　with　MnBi=80　wt%.　(C)　2016　Elsevier　B.V.　All　rights　reserved.
