摘要：

We　have　designed　and　prepared　heterostructured　(SmCo7/FeCo)/SmCo5　multicomponent　magnets　by　high-pressure　thermal　compression.　The　coordination　and　interaction　behavior　of　SmCo7/FeCo　and　SmCo5　phase　regions　during　high-pressure　thermal　compression　and　magnetic　reversal　process　were　studied.　The　introduction　of　SmCo5　can　improve　the　coercivity　of　the　magnet.　The　heterostructured　(SmCo7/FeCo)/SmCo5　magnet　with　30　wt%　SmCo5　content　shows　optimal　magnetic　properties　with　M-r　of　10.3　kG,　H-ci　of　6.0　kOe,　and　(BH)(max)　of　16.7　MG　Oe.　(C)　2020　Elsevier　B.V.　All　rights　reserved.
