In　this　work,　the　effects　of　Pr　content　on　the　structure　and　intrinsic　magnetic　properties　of　Sm1-x　Pr　(x)　Co-5　(x　=　0-0.6)　compounds　prepared　by　induction　melting　were　systematically　investigated　by　scanning　electron　microscopy　(SEM),　X-ray　diffraction　(XRD),　and　magnetic　measurements.　Microstructural　observation　and　chemical　composition　analysis　show　that　Sm1-x　Pr　(x)　Co-5　compounds　are　composed　of　(Sm,　Pr)Co　(1:5)　phase　and　(Sm,　Pr)-rich　grain　boundary　phase.　XRD　results　show　that　all　the　Sm1-x　Pr　(x)　Co-5　compounds　have　a　(Sm,　Pr)(1)Co-5　main　phase　with　the　hexagonal　CaCu5-type　crystal　structure　and　the　(Sm,　Pr)(2)　Co-7　impurity　phase.　In　addition,　the　detailed　research　shows　that　the　lattice　constants　(a,　c)　and　unit　volume　(V)　are　all　enlarged　with　the　increases　in　Pr　content.　According　to　the　magnetic　measurements,　as　the　Pr　content　increases　to　larger　than　0.4,　both　the　Curie　temperature　(T　(C))　and　the　anisotropy　field　(H　(A))　of　all　the　Pr-doped　compounds　decrease　rapidly.　Meanwhile,　the　magnetization　of　Sm1-x　Pr　(x)　Co-5　compounds　at　applied　field　of　14　T　(M　(14　T))　are　observably　improved　with　Pr　doping　content　of　x　＞　0.3.　Among　them,　Sm0.6Pr0.4Co5　compound　exhibits　slightly　lower　H　(A)　and　T　(C),　but　much　higher　M　(14　T)　than　those　of　the　binary　SmCo5,　indicating　that　doping　of　proper　Pr　content　into　SmCo5　compound　can　optimize　the　intrinsic　magnetic　properties.　As　a　result,　the　optimal　intrinsic　magnetic　properties　of　H　(A)　=　29.11　T,　T　(C)　=　989　K,　and　M　(14　T)　=　102.31　mA　center　dot　m(2)center　dot　g(-1)　are　obtained　in　Sm0.6Pr0.4Co5　compound.　The　effects　of　Pr　content　on　chemical　composition,　cell　parameter,　morphology,　and　magnetic　properties　of　Sm1-x　Pr　(x)　Co-5　(x　=　0-0.6)　compounds　were　systematically　investigated.　The　anisotropy　field,　H　(A),　of　Sm1-x　Pr　(x)　Co-5　compounds　is　depended　on　Pr　content.　Optimal　intrinsic　magnetic　properties　of　H　(A)　of　29.11　T,　T　(C)　of　989　K,　and　M-14　T　of　102.31　mA　center　dot　m(2)center　dot　g(-1)　are　obtained　in　Sm0.6Pr0.4Co5　compound.
