PROBLEM TO BE SOLVED: To provide a sputtering target for forming a magnetic recording film, which is used for forming the magnetic recording film of FeNiPt, improves pass-through-flux (PTF) on a target surface, and allows stable sputtering.SOLUTION: A sputtering target for forming a magnetic recording film is a sintered body having a composition expressed by a composition formula: (FePt)Ni(30≤x≤80,1≤y≤20). The sintered body has a constitution in which a FePt phase and a NiPt phase are dispersed. Existence of the NiPt phase showing no ferromagnetism improves a PTF on a target surface. |
