Description
The effect of Pt addition on the oxidation and corrosion resistance of the TbFeCo magnetooptic films prepared from alloy targets by d.c. magnetron sputtering has been studied. The addition of 5 - 10 at% of Pt to TbFeCo increased its environmental stability, reduced pinhole formation, and increased corrosion potential without significantly affecting the magneto-optical properties. Auger depth profiles indicated that the oxide on TbFeCo films after accelerated aging was thicker than that on TbFeCoPt films. X-ray photo-electron spectroscopy (XPS) was used to study in-situ oxidation of clean TbFeCoPt films under 5 x 10-7 Torr at oxygen at room temperature. Results indicated that Pt remained in the metallic form whereas Tb and Fe were oxidized at the surface. An oxygen-induced segregation of Tb to the surface was also observed
