The effects of Ar pressure on GdTbCo film characteristics without bias voltage were studied. Sample films demonstrated a large perpendicular anisotropy (Ku) which increased with the Tb contraction. In GdCo films, Ku became less negative as the Ar pressure increased, but Ku decreased in films containing Tb. Other results indicated that GdTbCo disks will be easy to manufacture.
