Correlation　between　Fe　content　and　z　value　on　the　structural　and　magnetic　properties　of　the　Sm　(CobalFexCu0.06Zr0.025)(z)　magnets　(x　=　0.20,　0.25,　0.28,　and　z　=　7,　9.5)　has　been　investigated.　It　is　found　that　the　cellular　phases　in　the　magnets　grow　up　with　increasing　Fe　content,　so　the　cell　boundary　phases　could　hardly　form　well　without　enough　Sm　atoms,　resulting　in　coercivity　decreasing.　After　supplement　of　Sm　content　by　decreasing　z　value,　cell　boundary　phases　formed　continuously,　and　coercivity　was　strongly　enhanced　due　to　the　remarkable　concentration　gradient　of　Cu　between　the　1:5H　cell　boundary　phase　and　2:17R　cellular　phase.　It　is　thus　suggested　that　as　the　Fe　content　increases,　the　z　value　of　magnets　need　reducing　simultaneously　in　order　to　keep　high　coercivity　of　the　magnets.
