PROBLEM TO BE SOLVED: To provide an FePtP bulk alloy having high coercive force. SOLUTION: The ternary alloy of Fe-Pt-P is in a bulk form and its composition formula exists within a composition range connecting Fe<SB>15</SB>Pt<SB>70</SB>P<SB>15</SB>, Fe<SB>15</SB>Pt<SB>50</SB>P<SB>35</SB>, Fe<SB>55</SB>Pt<SB>10</SB>P<SB>35</SB>, and Fe<SB>70</SB>Pt<SB>15</SB>P<SB>15</SB>, and is indicated by Fe<SB>100-X-Y</SB>Pt<SB>x</SB>P<SB>y</SB>(15<X<60, 15<Y<35) and a P<SB>2</SB>Pt phase not solid-solutionized with L1<SB>0</SB>-FePt phase and Fe is at least formed in the alloy structure.
