摘 要：Amorphous （Sm）TbCo/Cr films with perpendicular anisotropy were prepared by r.f magnetron sputtering. The magnetic properties and the effects of Tb substituted with Sm on the magnetic properties of TbCo/Cr films were investigated. After part Tb substituted with Sm, the RE-TM alloy film possess large perpendicular anisotropy. The substitution effects on saturation magnetization can be explained with the ferri-magnetical structure of RE-TM alloy film. By choosing optimal sputtering parameters and suitable Sm substituting fraction, the anisotropy constant as high as 4.15×106 erg·cm-3, the saturation magnetization above 380 emu·cm-3 and the coercivity above 4.5 kOe can be obtained at room temperature for （SmxTb1-x）31Co69 films.
