The magnetic and magneto-optic (MO) properties of facing Targets Sputtered (FTS) DyxNd5(Fe75Co25)95-x amorphous films were investigated. When x is over 12 at%, the easy magnetization axis is perpendicular to the film plane. The effects of various preparation conditions were also examined, both 470 K substrate temperature and - 100 V bias can enhance the uniaxial anisotropy of the films; substrate bias causes Ms to decrease and Hc to increase, substrate heating will have the opposite effects. These interesting results show that DyNdFeCo this films have properties similar to both Dy-TM and Nd-TM thin films. Furthermore, it is shown that the Nd component has a similar contribution to the uniaxial anisotropy as the Dy component in DyNdFeCo thin films.
