PrFeB/PrCo5　hybrid　magnets　were　prepared　by　spark　plasma　sintering　from　the　commercial　nanograin　Pr-2(Fe,　Co)(14)B　powders　(80　wt.%)　and　as-milled　amorphous　PrCo5　powders　(20　wt.%).　X-ray　diffraction　of　the　isotropic　Pr-2(Fe,　Co)(14)B/PrCo5　hybrid　magnet　shows　the　existence　of　the　major　Pr-2(Fe,　Co)(14)B　phase　and　the　minor　PrCo5　phase.　A　small　amount　of　a　new　Pr(Co1-xFex)(3)　phase　was　also　detected.　Both　coercivity　and　remanence　values　of　the　hybrid　magnet　lie　between　those　of　Pr-2(Fe,　Co)(14)B　and　PrCo5　magnets.　The　smooth　demagnetization　curve　of　the　hybrid　magnet　shows　that　the　hybrid　magnet　retains　the　characteristics　of　a　single,　hard　ferromagnet.　The　720　K　Curie　temperature　indicates　strong　exchange　coupling　between　the　Pr-2(Fe,　Co)(14)B　and　PrCo5　phases.　The　new　Pr(Co1-xFex)(3)　phase,　due　to　interdiffusion　between　Pr-2(Fe,　Co)(14)B　and　PrCo5　phases,　does　not　affect　the　performance　of　the　hybrid　magnet.
