摘要:
A study was made on the effects of elements substituted into the Cr layer on a CoNiCr/Cr sputtered hard disk. Among the various elements tried, Si, Gd, Ce, and Cu were found to increase the coercive force in the film. For Si and Gd, alloy targets of Cr‐Si and Cr‐Gd were prepared, and the deposited films indicated an increase of the coercive force by about 150 Oe over those without Si or Gd element.
