Abstract
Provided is a ferromagnetic material sputtering target containing a matrix phase made of cobalt, or cobalt and chromium, or cobalt and platinum, or cobalt, chromium and platinum, and an oxide phase including at least chromium oxide, wherein the ferromagnetic material sputtering target contains one or more types among Y, Mg, and Al in a total amount of 10 wtppm or more and 3000 wtppm or less, and has a relative density of 97% or higher. The provided ferromagnetic material sputtering target containing chromium oxide can maintain high density, has uniformly pulverized oxide phase grains therein, and enables low generation of particles.
