Abstract
A soft-magnetic FeCo based target material is provided which has a high saturation magnetic flux density and superior atmospheric corrosion resistance. The target material is a soft-magnetic FeCo based target material made of an FeCo based alloy. The FeCo based alloy comprises 0 to 30 at. % of one or more metal elements selected from the group consisting of B, Nb, Zr, Ta, Hf, Ti and V; and the balance being Fe and Co with unavoidable impurities. The Fe:Co atomic ratio ranges from 10:90 to 70:30. The FeCo based alloy may further comprise 0.2 at. % to 5.0 at. % of Al and/or Cr.
