Abstract

A ferromagnetic sputtering target comprising metal having a composition containing 20 mol % or less of Cr, and Co as the remainder; wherein the target structure includes a basis metal (A), and flat phases (B), containing 90 wt % or more of Co, within the basis metal (A), the average grain size of the phases (B) is 10 μm or more and 150 μm or less, and the average aspect ratio of the phases (B) is 1:2 to 1:10. Provided is a ferromagnetic sputtering target capable of inhibiting the generation of particles during sputtering, and improving the pass-through flux to achieve a stable electrical discharge with a magnetron sputtering device.
