SINTERED FE-PT-BASED MAGNETIC MATERIAL

摘要

A sintered Fe-Pt-based magnetic material which contains BN and SiO2 as non-magnetic materials, said sintered Fe-Pt-based magnetic material being characterized in that Si and O exist in a B- or N-existing region on a cross section of the sintered material. The present invention addresses the problem of making it possible to produce a magnetic thin film in a thermally-assisted magnetic recording medium and the problem of providing a high-density sputtering target in which the amount of particles formed upon sputtering is reduced.
