Patent ID: 8568576

Claim:
A sintered sputtering target comprising a ferromagnetic alloy dispersed with nonmagnetic oxide particles characterized in that: the ferromagnetic alloy contains a composition consisting essentially of 5-20 at % Cr, 5-30 at % Pt, and Co as remainder; the sintered sputtering target has a structure comprising a ferromagnetic alloy phase (A) in which the nonmagnetic oxide particles and particles of a Co—Cr—Pt alloy phase (B) are dispersed, the particles of the Co—Cr—Pt alloy phase (B) having a schistose shape with a short side length of 30 to 100 μm and a long side length of 50 to 300 μm; and Cr is concentrated to 25 at % or more at a central part of each of the particles of the Co—Cr—Pt alloy phase (B) and is lower in concentration at a periphery of each of the particles of the Co—Cr—Pt alloy phase (B).
